I'm not sure if those kids knew better, and were just straight out being little assholes or if they are like that in general at all times. The worst part was a parent of theirs was sitting a few feet away and was oblivious to what was going on. Or maybe she just didn't want to put her book down and deal with her rude mean and ugly kids.
Anyways, be nice to those around you. Be considerate too.
Tomorrow will be better. I know it :)
