I don't think I've really thought about this before but I've been looking at all the presents I've bought/plan to buy and I've noticed that a lot of the birthday presents are personalised/thoughtful gifts and most of the Christmas presents are useful as well as being nice presents.
I don't think I did this on purpose but it makes sense to have more personal gifts on your birthday as it's your day whereas Christmas is more for everyone.
Do you buy different types of gifts for Christmas and people's birthdays? Do you spend different amounts? Do certain people get better/more gifts than other people??
Would you pay less for a humanities degree?
