Is it a problem that I'm 16 and I drink alcohol before school all the time?
Will you continue doing that?
My parents don't care about me, so I can do whatever I want.
You shouldn't drink before going to school. Stop doing that now.
You are stupid. You think you are better than me because you are old and look down on me.
It will get you into trouble eventually. The teachers will smell the alcohol or you will become an alcoholic and do worse in school.
