Facebook Messenger

You know how Facebook has that feature where it shows your online friends and allows you to talk to them? Yeah, I hate that crap because every time I go to talk to somebody they're online, but then I say something, hit send and it says they're offline. I think it's like a bad form of AIM, because at least with that you can block people or just not give out your screen name. With the FB application however if there's a friend you have but you don't really want to talk to them and you both happen to be using FB at the same time you can't avoid the chance that they may say something to you. Now I do understand that there are some pages where you are unable to use it, but for the most part nobody is on those pages long enough for it to matter. I'm starting to think that some people just don't want to talk to me. They could at least man up and say I don't want to talk to you, that way I wouldn't waste my time. People don't understand that it's better to have somebody know that you don't like them than to have them think you're friends.
