So tomorrow I have to give my guest list to my hostess. I know there's nothing I can do about it but I just REALLY don't want to invite my DH's sister and aunt. His sister is just BSC and will most likely act like a childish brat (like she did at my bridal shower). We had a bad falling out a few months ago and have since been civil to each other but we certainly are not friendly with each other. The problem is, MIL is like her PR representative and would have a fit if she wasn't invited. It's just easier to keep the peace by inviting her. I'm keeping my fingers crossed that she declines the invitation.
As far as DH's aunt, she's just a crappy person. DH doesn't like her and doesn't like being around her, but MIL told her about the shower and is trying to insist on us inviting her. Her and DH had a HUGE fight about it. Again, it's one of them "keep the peace" invites at this point. No point to this post, really. Just b!tching and moaning.
Re: Just whining.
That's all you can do at the end of the day. At least you know you're doing the right thing - if you didn't invite, imagine the drama!
You did the right thing.
Do you have one of those friends who is totally cool and collected, but not above putting someone in their place? Enlist her to keep an eye on the SIL and Aunt and step in if they start to get out of hand.
Sometimes a simple, "Now, now, this is Jane's day ladies" said in a slightly condescending way from a stranger will do just the trick.
