I can be quite selfish. 'Recent' issues in my life which have caused me to be majorly stressed out at times has amplified this in me. Not that I don't care about others or never help others out, it's just that I put myself first a lot of the time, even when it's not the best for others. I don't do it intentionally, it just happens.
I'll have you people know that I started off on the internet at a Sonic the Hedgehog forum and... you're all pretty much right. If I have to hear someone whine and moan about "green eyes" or "sports tape" again...
As for the worst bad thing I've done... hmm... I would be breaking the rules if I said that... and that too... and that... oh, that's probably illegal in 40 states... nope, can't say that...
Oh! One time I did run around a friend's yard clucking like a chicken with no pants on because she dared me to do it. Let's just say that the ends did justify the means in the end.
