I just called TIB's house. No one was home, but I left a message on the answering machine asking if we could get together to talk and "get this whole thing sorted out, before it spirals any further out of control". Ummmm, probably not the best choice of words, now that I think about it, but at least I made an effort.
Now the ball's in their court. Hopefully TIB will not show up tonight at my place with a baseball bat. Although if she came unarmed, I could totally take her in a fight.
