Hi all, wondering if I should invite my partner's sister to my hen's. She's much older than me and my friends (I'm 35 and my friends are that age or younger, she's 45) and in a totally different place, even mentally. My friends are used to going out and having a good time, she's a home maker and has always been the 'good girl' type... I have nothing against her but I want to be relaxed at my hen's night and not worrying about whether someone else is having a good time. On the other hand I don't want to offend her... Also, her husband's brother is getting married some months after us and his fiancee' is also the good girl type so I'm sure she'll be invited to her hen's night... Help!
