Writing as a teenager

It is sometimes not easy as a teenager to have the right words when they have to write something. For example in the school, teachers require the right word choice! Also a problem is that the young people are just writing an their “young” slang with their friends like “Sup” instead of using the right word “What’s up?”. Also teenagers lose a lot of points in their tests because they have more and more grammar and word problems which they use. The only thing which is motivating that the teenager’s will lose their slang after a while. Everybody was in this time and the most of the adults got their right writing after their teenage time.
