Worst present I ever had was from a friend a couple of christmases ago, who frankly I always bend over backwards to get lovely thoughtful presents for despite having a LOT less money than her. It was a pair of travel slippers 3 sizes too small for me, with the price still on, that looked very much the worse for wear, leading me to believe she'd been given them the previous christmas and didn't want them. She knew perfectly well I had a couple of pairs of slippers and didn't need any. Charmed, I'm sure. I'm kind of tempted to do something similar this year to make a point. Maybe that's vindictive but I was really not impressed.
I remember reading a thing in a magazine years ago about terrible presents, and this one is so ridiculous I've never forgotten it. This girl's boyfriend of several months had wrapped her up, for christmas, an open jar of jam from their fridge. As her only present. What the...?
