How do I manage to constantly make an ass of myself?!

So I'm trying to do a good thing tonight by deleting EtCMOB's email from my contact list. I am seriously prone to accidentally emailing the wrong people and various other retarded stuff like that, so I thought in an attempt to never accidentally bug him, I'd take him out of my list. I mean, I wouldn't put it past me to try to send Courson an email and accidentally sent it to EtCMOB instead. So I'm playing with the quick contacts list on gmail and somehow managed to accidentally send him a chat invite. I'm so embarrassed. Why does this shit happen to me all the time?!
I really suck at living sometimes!
