I too am in this very crowded boat.
I tried taking another female friend, no she doesn't want to know.
She would actually mail me my own genatalia if i lit her up when she wasn't looking,
I think I just have to sit back say ok she aint going to do it and stop whining.
Turn the tables would you go on a 9 hour shopping spree with her? I let her go on her own unless I know it is a one item shop, even then it bores me stupid and i end up standing by a pillar on my own, imaging each clothes rack to be a bunker and how i could use it to my advantage. I hate shopping she hates paintball.....
ohh well
