Hi ladies,
H's Dad and SM were the only set of parents who gave us a gift at the wedding (my parents and H's both made contributions to the wedding itself). All parents were already given a card and gift at the RD. FI has already verbally thanked them for their gift. Should we also send a physical TY note? Part of me feels that it is no different from any other gift, but part of me thinks it is overly formal to send a TY to parents. Either way, I am definitely over thinking it, so please set me straight. Thanks!
