Last week, my FIL asked H for a list of what/how much his friends and family gave us as wedding gifts. He wants it as a reference for gift giving in the future. I told H it's none of his business and he shouldn't base gifts on what others gave. Well, he called again asking for the list, and I don't know how to say "none of your business" without being rude and was wondering if anyone has been in this situation or could offer any advice. TIA!
