Bye bye Tahiti 😭🏝️

Vista from a restaurant elevated from the ground. In the foreground is a swimming pool surrounded by palms trees, then a bridge and a saltwater pool and some bungalows on the water. Finally, we see the ocean, the island of Moorea just off of Tahiti, and a majestic cloudy sky where the sun is just beginning to set.

Break from packing the kitchen

He will lie down literally on any rectangle (also last day here as we move to the Airbnb tonight. We’ll be back to pack and clean so we’ll still see him but 😭😭)

Five more days at this house with this cat before we spend a few days at an Airbnb before coming back to the US 😭 I’m going to miss the neighbors’ cat so much when we leave.

A striped orange cat lies on the armrest of a couch with his eyes closed, looking like a perfect angel. In the background is a patio door to a large deck with chairs, a table and some plants.

Universal subsidized childcare pays for itself in increased tax revenue from women who work and lower child poverty. We can have childcare that is affordable for parents AND is high quality and for which the providers are well paid. Both screenshots from www.theguardian.com/us-news/2025...

Black text on white background:

"The system pays for itself - it brings women into the workplace and they pay taxes," said Fortin, a leading expert on the economics of subsidized childcare. "You get more money flowing into government coffers." This extra tax revenue actually exceeds what the government initially paid to establish the universal childcare system, he said.

Fortin, who has written papers showing how this policy creates "fiscal surpluses", attributes women's growing labor force participation directly to the introduction of low-fee childcare.

Today, Quebec has among the highest female labor force participation rates in the world right next to Sweden, while the US lags more than 10% behind. In addition, the gender pay gap - the difference between the earnings of men and women - is smaller in Quebec, where women typically earn 91 cents on the male dollar, than the US, where women earn just 85 cents.

Black text on white background:

Measuring the causal impact of Quebec's subsidized childcare on factors such as poverty and social assistance is an imprecise science, but Fortin points out that the number of single-parent families on social assistance in Quebec plummeted by more than 50% in the decade following the reform. Today, Fortin calculated exclusively for the Guardian, that Quebec has 75% fewer single-parent families on social assistance than it did in 1996.

It's also had a tremendous impact on childhood wellbeing. In 1996, child poverty rates across Canada were at an all-time high and children in Quebec were among the worst off. Today, it's the opposite. According to the most recent figures, Quebec's child poverty rate was 44% lower than all other Canadian provinces.

Fortin estimates that poverty in Quebec decreased by more than 60% in two decades, but points out that universal childcare wasn't implemented in isolation, but alongside other important social policies, such as enhanced parental leave (now up to 55 weeks of paid leave), high rates of education and employment and pay equity legislation.

Perfect loaf, and in a conveniently labeled box!

Since then the American aisle at Carrefour has come through but psychologically I can’t spend almost US$30 on Skittles in one go, I’m just weak I guess 😔

In a grocery store aisle, a 3 pound 6 ounces container of skittles at a price of 2795 Pacific francs. Behind the price is some 100% American branding. Parts of other products are visible on the sides.

When husband plays the new James Bond video game and I’m helping

On graph paper, a series of algebraic equations in the variables x, y and z. The first two equations are x equals y plus 2 and y equals z plus 2, with the resulting equation x equals z plus 4 next to it. Then under it is the equation z equals x plus y minus 2 and x plus y is circled with the word “combined” under it. Then under that is the equation z equals 10 x plus y minus 2, which is 10 z plus 40 plus z. This is then solved as z equal 4, x equals 8 and y equals 6, and below is the number 1864.

One thing I love about Tahiti is that if there is a lot of traffic you can usually go on FB and get a photo of what happened. Today’s situation: big truck stuck. It’s been there for about an hour according to the internet.

In the distance the back of a trailer truck is stuck under an overpass. There are two cars going in the opposite direction in the foreground and tons of people on the overpass looking.

I felt bad posting about them without pics so I snapped some for the good people of BlueSky. Behold the dogs of Carrefour! These three have been near one side of the Carrefour every time we’ve been so far.

For example witness this adorable tiny plow. Don’t tell me you couldn’t have a bunch of these and having them would be more expensive than an equivalent number of the big ones

I heard that cats like to eat from full bowls so I thought why not let him eat straight from the food container? But now it’s too low for him to eat comfortably

Orange striped cat on a table with a giant plastic bin of cat food, eating from the lid of the container where I poured some food because the bin is no longer full. Behind him is a game of code breaker/mastermind.
