thank you for gift from people who were not invited
About a month after our wedding we received a cash gift and card from an aunt and uncle I am not at all close with. In fact we have had a fairly rocky history so they were not invited to our wedding. I know I will send them the "thank you for the generous gift, it will come in handy with...." but after that? I got nothing, my other thank yous I filled out the card with inside jokes from the wedding or how happy we were that they could share in our special day, but I have no idea what I would say to these people. This will probably be the last correspondence I will ever have with them. How can I be polite while not telling an outright lie "ex we wish you could have been there"
