I did that yesterday with my BIL. I think he is irked but... he literally gave me 4 hours notice. I suggested maybe another time.

Sometimes I curse Facebook, for the exact opposite reason that one might think... that it is just too easy for people to reach out without thinking. I have reduced my Facebook to just family now and even with 22 people I seem to get this problem.

I wish I could do a status update explaining my situation and telling people that if they want to go out with me they need to come over and do a chore first. That probably would stop it...but, then also shock everyone.
