We were "missing" wedding cards/gifts from about 10 people after we got back from our HM. Two people have since given us gifts. And a couple others we can understand why they didn't (cousins in their early 20s and maybe they thought their parents - our aunts/uncles - signed their name on the card or something). But there are 6 people we can't figure out. Now, times are tough right now I understand. And people can't afford gifts, but nonetheless, a card would be really nice. We got a couple of cards where people just signed their name - no gift. That is 100% GREAT. I LOVE those people b/c now for the other 6 people I just can't figure them out. Did they leave a card/gift that got lost? Do I send them a thank you card with the rest of the thank yous that just thanks them for coming to the wedding? Or do I wait awhile b/c maybe they are taking advantage of the year rule (though I know them and they don't strike me as that type)? Some of these people are very close (grandparents!) and I don't want to offend anyone. WDYT?
