Is Bella Goth ever at home?

I swear, almost every world my Sim visits, Bella Goth is hanging around. Oasis Springs, Brindleton Bay, Henford-On-Bagley.
My Sim is doing karaoke in the city of San Myshuno at 1:00 a.m.? Bella is there.
At the bar in Glimmerbrook? Bella walks in the door.
My Sim is in the scientist career and can't even get to her job location unless she is working. But oh look, there is Bella outside on a random Thursday afternoon, seemingly going for a jog.

domestic life doesn't seem to suit her...
