How do I approach tomorrow's exchange?

This is the first time I will go in knowing the full extent of what has been going on.

Last week's exchange I was very short and got out of there quickly.

W asked me how trick-or-treating went and complimented me on the new jacket I was wearing. I told her it was the best halloween I've had in a long time and said "mmm hmm. to the compliment... and then focused my entire attention on saying goodbye to my S.

If she tries to communicate at all with me, I think she will try to explain what happened when she was caught w/ OM.
