I think I'd go back to 2 days ago and tell myself to get my ass to bed so I wouldn't end up feeling too damn groggy (and with sore eyes from the 36 hours of contacts in) and miss out on my sister's fiance's Punk Band's CD Release Party at a rockin' bar.
Honestly... I think I would spend it there. Even if I went back in time... I'd shrug it off soon enough, so I'd have to go back... what? within a week of whatever i was trying to prevent?
Of course if I prevented it, then I wouldn't have gone back in time to prevent it. So do I get to go back in time again? or did I waste my venture preventing something that never ever happened?
Welcome to my mind.
[edit]Oh, here's something I would like to do. Go back about 4 years ago and since i gotta talk to myself... I'd tell myself to get my uncle to the doctor for a coloscopy... so he wouldn't be so weak from the chemo now and wondering how much time is left.
My mom just spent three weeks up there with him (her brother). I may only have a week left to see him... he lives 9 hours away. [/edit]
