I happened to be sitting with my daughter and her husband as they opened the cards. Most couples gave $150. This covered about the cost the whole thing per couple. That was nice.
Back in the day (30 years ago) it was great to get $50.
Younger people have a good idea of the costs, as it is a common point of discussion. The parents generation knew because we’ve been involved. The grandparents did not have a clue. (It was kind of cute to see how out of touch they were—but that they did better than what they thought they should give.)
Gifting at weddings is not the topic here. I don’t think anyone was invited, expecting a gift or a return on investment. They were invited to share in the joy.
Then you've never been to an Italian wedding, they keep lists and have long memories :)
