"You wanna go uptown for a drink after work?"

Ahhhhh,I'm sure all of us have heard this question on a Friday night after work

For me,most of the time I'd rather just pick up a 6-pack of Heineken,come home,kick my shoes off and relax.

my co-workers constantly harass me about head'n up town,which I do occasionally but whats the big deal if I wanna just head home after a long week?
