Specifically because of my wrapping paper thing. If I had just ripped off the wrapping paper it wouldn't have been that annoying, but they knew I'd make it more difficult for myself.
This isn't really about the gift itself, but I'm one of those people who can't bring themselves to rip the wrapping paper off of gift, I have to go and carefully remove each piece of tape. My parents once gave me a huge wrapped present... inside was a slightly smaller wrapped present... I swear...
