Well after an hour or two of getting used to the fact that I've actually swiched bodies with someone... I'd probably get dressed, cos I mean... Although it's my borrowed body, it'd still be gay to see it right? So then I'd leave the house, nothing more scary then having someone say hello to you and you have no freaking clue who they are.
At this point, I'd probably go out, drink a lot, and hope that whatever the hell I took last night will wear off soon!
