We're getting down to the wire! And my darling FH has left writing thank you notes to his groomsmen and parents until the last minute. Some background: FH is not close with his parents and their relationship is a bit complicated. I'm very close with my parents and wrote them a pretty long letter about how much they mean to me. FH asked to read it so he would have something to go off of, and is now struggling because he doesn't feel the same way about his parents. (e.g., I wrote about how they made me the person I am today and their unconditional love means everything to me and some other mushy stuff)
For those of you who are not as close with your parents/FH's parents, what (generally) did you write in your thank you notes?
