That's really horrible. Those teenagers most likely don't understand why these people are homeless. They think just because they have no place to live that they are less of a person and that the same rights don't apply to them. They probably see the homeless people as an easy target to pick on and look 'cool' for doing so. Especially because the homeless people don't fight back from the abuse.

I really do think humans these days have less and less common sense. They don't treat others with any respect. They don't care for the environment or stop to think. When I was at the zoo I was disgusted at the stupid humans there. They were throwing chewy sweets to monkeys and giving muffins to them too. I mean, those monkeys are from the wild! Do they think our junk food is good for them? They'll go eat it, along with the wrapper and be sick and get ill. How can they be so insensitive? So I wrote before going out of the zoo on the sheets they give you to say what you liked/didn't like/suggest for the zoo, that they should put the humans in the zoo. Humans treat animals like dirt, and now humans treat humans like dirt. I can't believe they have the nerve to act like that. >.<
