Hmmm. I'm a bad RSVPer. I'm a last-minute one, but I don't change my mind. I will give an INTENTION: we want to come/we may not be able. But due to DH's job, we don't know until a month in advance. For going out to dinner, not usually a problem. A wedding, more of a problem.

My sister and her mates make about four arrangements for one evening then pick the one they want the most or the one that hasn't been cancelled for better plan. That's the norm for them and it's accepted. I was horrified when she told me that she'd had three texts cancelling when she spent an evening with me: if they hadn't have cancelled she'd have cancelled them. OK so I was top but even so!
