The other day I got an e-mail from W asking if I would be open to going to her bosses vacation cottage for the day sometime in August. I said I would be open to it. Then she says that OM was invited by the boss too (and probably OMW too.)
I don't know if your presence is or is not important to her job security, but if not, I would politely decline and say I have other plans. Wet is right. That should be a boundary.
