Our wedding was about 6 weeks ago and we've been back from our honeymoon for about 5 weeks now. I completed all of our thank you notes for gifts within the first 10 days of getting home. I noticed that a few guests didn't give us a gift, but certainly didn't get upset and I wouldn't even consider saying something as that's ridiculously rude. But yesterday I was chatting with a friend who attended the wedding and she asked if we received her gift in the mail when we returned home. We hadn't and she was one of our guests that I thought hadn't given us a gift. After she said that I realized there could be other gifts that just never made it to us due to the post office. We had all of our mail held while we were gone (for about 10 days). I plan on going to my local post office tomorrow to ask but I doubt they have anymore mail for me just laying around. How do I ask my guests about this without sounding like I'm asking for a gift? Or should I even say/do anything? I would feel horrible if someone sent us a gift but they never received a proper "thank you" because their gift never reached us.
