COSTCO

I played truant from keeping a dialy for two days...
Friday, we ate dinner at a beef  barbecue restrant, and yeasterday, we went shopping at COSTCO. We bought a lot of food such as a big cut of beef, 3kg of light and strong flour, spaghetti and some spices. There is one thing I've been wondering. A lot of people bought very expensive toilet paper at COSTCO. What are they?? What's the difference between expensive ones and normal ones?
And then, I went to a hair salon. I had my hair cut short!

Yesterday's dinner menu was 'temakizushi'. I don't eat 'normal' rice so much, but 'vinegared' rice is different...
I ate too much.....
