My sister-in-law recently received an invitation to a Christmas party to be held on Christmas day from her "friend" Laura. The invitation said "no children please".
Now, I don't have children and am very sympathetic to those who would rather not have kids at their parties. My SIL does have 2 children, but has always been very respectful of the adults vs. family events issue. She has happily attended many weddings, birthday parties, showers etc... without her kids when they were not invited, so I know she had no problem with the party itself. However, because the party was on Xmas day, she felt that she should be with her family on that day, and so politely declined the invitation.
Laura then calls her and starts screaming at her, saying she is "obsessed" with her kids, that she "hates" people who don't have kids, and that she is ruining Laura's Christmas by not attending the party. My SIL, who is the sweetest person ever, called me crying and convinced that she was acting horribly. I pointed out to her that 1) Wanting to be with family on Xmas does not count as obsession! 2) I don't have kids and she has never acted as though she hates me, and 3) Regardless of whether or not the invitees had children, Laura should have expected a high number of declines from people when she chose to have her party on Xmas Day! I sure hope SIL crosses Laura off her "friends" list.
Asharah's comment: Okay, I can understand no-kid events, but a party on Xmas day? Xmas has always traditionally been a family oriented holiday. And screaming at somebody for ruining the party by not attending? Talk about tacky. I wonder how many other people with kids didn't attend.
