We had a wonderful ceremony & reception with 200 of our closest friends and family in attendance. It was amazing, and nothing went wrong, but quite a few people didn't get us a gift or even a card; but that is not the problem, I understand the tough economic times. The problem is I am not sure if they didn't bring a gift or if my sister stole the money from the cards and threw the cards away. My sister, who was a bridesmaid, has a problem with drugs and has stolen from my entire family in the past; everything from pawning our jewelry, taking our change, taking money from our wallets, and anything else she can get her hands on. My question is do I ask the guests about the gift or just drop it? I am about to start writing thank you notes, and will still write one to all the guests just for attending. Do I just keep it general and thank them for attending? The last thing I want to do is seem gift hungry or upset about not getting a gift, but I have to wonder if my sister just stole some?
