You can't avoid her forever. Better that you're prepared for it than for her to just unexpectately show up on your doorstep. Do some yoga, take some Xanax and go over there.
your right, W will likely ask if i reacted with anger/dissapointment etc.. I will goto the gym tonigh, i have allready called SIL and she said "can i call you back,are you at work??" weird question but said sure.
I am sticking to my plans for Saturday ( I have to build a temporary dog run during the day (new neighbors moved in last night, then going to yoga then suntanning on our lake, and then comedy club with my buddy Sat night(i won some passes))
Sunday , i am going hiking in the mountains with some friends.. when i get back i am going to the gym.
Monday I can give her a hand, and will likely get served, it's how i choose to react that's important. I don't know if i will say "ok thanks" or what i'll say.. i just have to keep it in my head "it's just paper".. nothing more
How i can accomplish that.. well.. not too sure yet
(SIL's BF likely knows everything and i play squash with him friday night, do i mention that i know? I suppose not)
