Most of my friends hate the shopping part of Christmas. I, on the other hand, love it. I love choosing presents for people - picking the perfect gift for someone, or making a present if that would be more appropriate. I even spend time choosing something special for relatives that I'm obliged to give gifts to - if I'm going to spend money on them, I may as well get something appropriate.
What I hate is wrapping presents. Wrapping one present is just a pain. Wrapping many is tedious. And then wrapping them in protective packaging: bubble wrap and boxes, to keep safe in the post is just... mind-numbingly boring. Plus all the dust from the paper makes me wheeze. Blah.
