My husband and I did not have a registry for our wedding, as we didn't want to "ask" for anything (not to mention we were already living together in a small space). We did set up a Honeyfund for money that could go for a house in the future, but we labeled this as purely optional.
Most of our guests actually did end up giving us something in some way or another (Honeyfund or a random funny gift), but as we were writing out thank you cards, we were a bit surprised to find that my husband's family (we'd invited his parents, grandparents, aunts, uncles, and cousins) did not give us a single thing, not even a card.
We did not expect to receive physical presents or money from anyone at all, but not even a card from the groom's family?? Is this weird?
