My friend and I are always on the phone. It never fails that while we are on the phone, her phone will hang up, sometimes several times lol. She feels so bad about it, but I just laugh. Well today it didn't hang once, it did however call me twice while we were on the phone lol. I told her that her phone is bipolar towards me, it don't know whether it likes me or hates me. She said "now that I think about it, it don't hang up on anyone else like it does you"... Lol.
