There are so many counts on which your friend was sorely, sorely out of line that I’m not even sure where to begin. I mean, there’s the fact that it’s pretty common for people to mail gifts to the couple just after the wedding, and under no circumstances is it required for any guest to show up at the ceremony and reception with fancy be-ribboned package in tow – yet here he is, just days after his wedding, making lists of who brought gifts and who didn’t and personally calling up the supposed etiquette offenders to tell them why they suck? Doesn’t he have anything better to do – like, oh, getting lovey-dovey with his new wife for instance? Then there’s the fact that even if a guest does happen to forget to send a gift, one should simply have the grace and sense to be happy that they took they time away from their hectic lives to come and celebrate in the special day. 

Which wasn’t even the case here, since you actually had a gift in hand even, but simply forgot to leave it with them the night of the actual event – understandable, considering the fact that your husband was involved in the wedding and undoubtedly simply got caught up in the excitement of it all.
