Would you invite your SiL to be on your hen do?

[MrsWembley]

If you've known her for the best part of 20 years, always got along but never been particularly close?

Yes definitely, unless it was going to be a really select gathering. I'm guessing you haven't been invited?

Actually, it's my hen, and I was asked about her today, which is when I started thinking 'Will she be surprised or expecting it?'

We've always got on, just not in the phoning for a chat/going out for a drink kind of way. And I should clarify, not my SiL, rather DP's (brother's wife), but I've always referred to her as my SiL as it's easier

Went to DB's wife's hen, wasn't invited to BIL's wife's hen, seemed a deliberate snub which I was quite hurt about although she was never invited to mine as I hate her didn't think she would get on with my friends.
DB's wife was invited to mine though but it wasn't her sort of thing, so didn't go.
