Anyway your dad can drop you off at the grocery store between your sister's and the bowling alley and then you can take a cab home or something?
I'm on my way to the grocery store now; anything I can pick up for you

It's right down the street and has my pharmacy and everything. Very convenient and quick.
I don't necessarily mind the "time" out but some of the activities can wear on me so I wish I were home. Maybe you can find some activities/places near the bowling alley that would be easier/better for you (library?) to wait at.
