I always loved going down to the forest to pick the Christmas tree when I was a kid (Tyrebagger forest near Blackburn, for any Aberdonians, is awesome!). My parents/brother never got a look in, it was always my decision. We'd spend about an hour trying to find the perfect one. It was always stupidly big, and every year my Dad would have to cut it down so it would fit in the living room.
Tempted to get a tree this year, but I'll be in Prague for Christmas so not really much point. I've hung up some lights though, they are pretty.
