Identifying nicks?

There is something I just can't understand. The nicks we have in MSN, for instance, should be useful for other persons to identify us, when we log in, right? So, why do people insist in signing in with nicks like:

- I'm going on holidays to Hawaii! Just look at how lucky I am, la la la...;
- Hawaii was canceled. Just my bad luck, I'm going to have to stay here, like any ordinary portuguese, la la la...;
- My life just isn't the same, love you very much, Manoel;
- Congratulations, Cindy!;
- There are people so stupid, I'm not in the mood to stand this;
- Love is such sweet sorrow, when you lose someone you love;
- Love is a fire that burns without being seen...;
- My soul hurts, goddamit!;
- I'm here, ho ho ho;
- Follow the white rabbit;
- Be careful what you say, because things you say can turn against yourself and then you loose the ones you love and you don't know what to do, you bastard! Have you seen the shit you got yourself into?;
- What the eyes don't see, the heart doesn't feel;

And then they get very upset because: "I'm here for a long time and you don't even speak to me!". And I'm supposed to guess who they are? Do you truly believe I click on every single weird nick that pops up, just to see who it is? Bah!

P.S. - Upsy! I think some of my friends are going to be offended with this post...or then again, not!
