My kids always open in front of the giver. They ALWAYS say they like it, and thank them, rather they liked it or not. They know it is rude to say that you don't like a gift. They say they liked it and thank you and move on to the next. We also always send thank you's. My kids are 10 and 7 and they have been writing their own thank you's since they could write. I feel it is the right thing to do.
