What is the nickname of london's underground?

The nickname of London's Underground is tube.

Hi! I'm glad to hear from you! It's been a long time since your last letter.
So, you prefer desingers' things. I like to look fashionble, but I don't want to spent lots of money on clothes. Besides, present-day fashion can be extraordinary sometimes. Top models on the cover magazines or runaways look amaizing in such clothes, but wearing something like that in every day live may look very strange. As for me, I prefer comfortable things, that matches me. I can choose anything from jeans and T-shirts for weekends to beautiful dresses, when I go to the party.
I prefer to do shopping with somebody, for example, my sister or friends. Sometimes I also go with my parents. My mother and I have different styles, but she likes what I choose. There's a big supermarket in our town, so we often go there. Clothes are at acceptable price and have good value. Sometimes we call at several small brend stores.
I've read about your situation. I think, you should listen to the parents. Imagine, they have to pay for many things, like house, meals, your aducation, clothes for you and them. There's no need to buy the most expensive clothes to look fashionable.
Now I'm going to my friends. I've been invited to the birthday party.
I'm waiting for your next letter.
Best wishes.
Kate.
