most people are there just trying to have a laugh...nothing wrong with that...

i notice you've only been a member since May (1 1/2 months?)
i've heard (seen?) some pretty intense conversations on chat, involving abuse, self injury and suicide..as well as some sexual joking around.
i agree if it's light hearted it doesn't matter much who is participating but when the chat turns intense, you tend to take a little more notice of who you're chatting with...that's all.
