You need the nightlife expansion pack

wat the hell is that??!

Actually like what he said or she said u need a night life expansion pack a night life
expansion pack is where sims disco and go anywhere during the night teen agers can sneak
out something like that and if u already have is to type this ctrl+shif+c and there will
be a small text box and just type there boolProp testingCheatsenabled true be sure 2
follow what i placed the or u will go over and over again the hold shift and press on ur
sim and click spawn... and the clik more if it still doesnt show up just click more and if
u dont want to use the cheat u can just go to a community lot at night in night life u can
possibly see a vampire be sure to make friends with the vampire or flirt with the vampire
and get married and when ur really close the vampire has the possibility to bite u and
wala! ur a vapire oh and i almost forgot wen ur a vampire ur sims mood will become lower
in the day and ur sims cant go out in the day they must stay inside their coffin all day!
i hope this will work!
