My good friend asked if she could throw my bachelorette party and wanted an invite list. I have 8 close friends from various stages of life whom I’d like to invite...and then there’s my sister-in-law. We get along well and I like her—but we don’t really hang out outside of family gatherings, so I feel like she’d be the odd one out at my party. All of my other friends have met over the years, so while they aren’t friends with each other, they do know each other. Should I invite my SIL? Tell her she can bring a friend so she’s not flying totally solo? (But then have a semi-rando at my party?)
(Side note: most of us live in the same city and the party will be local, so I assume everyone invited will come.)
