My mum lost two of dad's gifts, looked everywhere but couldn't find them, then wasn't sure if she may have even forgot to bring them home at all. Broke down into tears and didn't stop for the rest of the day for various reasons. Then she gave dad some tickets for a show, and got nothing but a douchey response which set her off again.
I'm not a scrooge or anything, but I'm just over Christmas. It's more trouble than it's worth in this house. I don't need gifts, and get nagged all month about what I want. The bad outweighs the good these days.
