Our problem is introducing the parents.
It seems to go on and on trying to describe
who we are to each other.
Son in law’s uncle/aunt ?
Have you thought about an assassin? It would be simpler.
Actually, how do any in-laws introduce each other? There isn’t a word, really. People just say, ‘and this is my daughter-in-law’s mother.’
If anyone needs any more explanation than that, it’ll be because they’re good enough friends that you’re going more in depth.
‘My daughter-in-law’s mother..’ ‘..happens also to be my son-in-law’s aunt.’ I think it’s a kooky story and kind of funny and more power to ‘em. :)
