Teenagers and Young Adults

I noticed teenagers and young adults in the mid 1990s or something would get upset at me, like if they do something and you don't give a friendly reaction.  I would just feel embarrassed, on the spot but then look shy.  Still, you'd be treated like you're bad, like "trash."  They act like you're not cool and they all keep doing these things.  They're all mad at Mommy and Daddy issues to kids, even good ones.  Bad kids seem to get away with it, sometimes.  I mean kids when I was younger, like maybe 12 I 1998? and older.
