Ответ:x=-5

First of all, buying clothes can be expensive. We would have more money to spare if we bought fewer
clothes. Wecould spend the money on fun activities with our friends instead, or save it for something
important, such as university,
Secondly, if we thought about how we behave more than how we look, everyone would be much nicer.
There are lots of magazines telling us what we should wear. I think there should be more about how to be
kind and how to help other people instead,
And finally, what about finding your own style? Everyone is different and it can be fun trying something
new - you don't have to be fashionable to look good! So, come on, don't worry about fashion - just be kind
and enjoy yourself!
Are the sentences True (T) or False (F)?

Everyone wants to look good, and I think some of my friends would wear something new every day if they had
enough money. People say that how you look is important, but I think we would be happier if we worried about
fashion less.
