What are bad things teens do?

This is a rather vague question as teens have been known to do about all the same bad things adults do. However, not all of them do such things. For instance, some teens do drugs or drink. Some have sex. Some shoplift. Some go for joyrides in other people's cars. Some do dangerous stunts or have dangerous "games". A few kill people. Some also die at that age, which is also a bad thing. The point is, teens are a cross-section of the general public and do things that are representative of greater society.
