Subject: What do you think about it?
Hi Vicky,
Today was the first day of school, and the first day I had to wear our new school uniform. I hate it!
Our uniform is awful. The fabric is scratchy, and the color is dirty brown. Yuk! What I really hate is that I can’t wear any of the new clothes I bought this autumn. I’m crazy about some of the new fashions, what about you? I especially like anything with stripes. But I can’t wear them to school.
I can’t remember, do you have to wear a uniform to school?
Write soon,
Masha

Hi Masha,
Sorry you don’t like your new uniform, but I have to confess — I love our uniform. I’ve always worn one, ever since the first grade, so I guess I’m just used to it. Here in the United States our local school districts make the decision about things like uniforms, and I guess ours decided it’s a good thing. The idea is that this way all students look the same — rich kids, poor kids, cool kids, not-so-cool kids.
Fortunately, we have some choices with our uniform, either dark grey trousers or a skirt, and then we have three different blouses we can mix them with. It’s really not bad. It makes dressing every morning pretty simple!
I figure I’ve got the weekend to let my style go wild. I agree — the new stripes are amazing!
Write and tell me more about what you’re doing this year.
Vicky
