Is it rude to respond "maybe" to an invitation?
Here's the situation: Two friends are hosting Canada Day BBQs on the long weekend.
Janet hosts one every year at her parents home (they have a pool and graciously open their home to Janet's friends every year, even though Janet is long-since married and moved out). This has been an annual event since Janet was in high school. I've attended for the last 7 years.
Janet sent out invites last week. I RSVP'd yes. She has set her date for June 30 with July 1 being the rain date.
Katie, who is not at all in the same social circle as Janet, just invited me to her Canada Day BBQ, which she is holding on July 1.
If the weather cooperates and both days are nice, we could and would attend both. However, if it rains on the 30th, we are already committed to Janet's party.
If it rains both days, Janet will do an indoor party.
Is it rude to RSVP "maybe" to a second invitation? Should I explain to Katie that I will be attending Janet's party? She knows Janet, but was not invited as they are barely acquaintances (they know each other in passing through me). I am the only person invited to both, as these are entirely separate social circles.
This is not a case where Mr K and I can split up and each attend one.
If I cannot attend both, I'll be sad about missing the one I don't attend. I'm pretty truly stuck and am really hoping for awesome weather both days so I can do both.
