I have started to stage a rebellion against lists personally. Go on, ask me for a list, here's what you'll get:
Something for the kitchen/cooking
Some sort of soap/lotion/manicure/pedicure spa-like stuff
Clothes, indoor or outer wear or accessories
Books, fiction, non-fiction, how-to, or humor
Art (visual, musical, theatrical, other)
Something for the car
Something for the cat
So ha! There you go, you got a list, but really you still need to pick something out. Because I can say the very best gifts I've ever gotten were total surprises. From the random but actually awesome set of 40 colored permanent markers, to the gold (colored) belt, to the olive oil mister, to the road flares for my truck, these were all awesome gifts that I didn't know I wanted until I got them - and now I love them and appreciate them!
And in that vein I do like if I get a general idea. Camping stuff, guitar stuff, cooking stuff, art supply stuff, science stuff, gaming stuff - a general category is helpful and fun. A specific list of specific brands and precise items? It just rubs me the wrong way.
