Christmas pisses me off.
I'm not Christian, but if I didn't celebrate this holiday that I don't believe in, everyone (family, my wife) would give me a ton of crap about it. My wife is even pulling the Santa crap with our son, when I really don't like lying to the kid. Whenever I suggest that we should drop the whole thing before he gets too attached to it (he's 3, if we let it go this year, he wouldn't even notice, but next year it will be too late) she says she doesn't want to ruin it for him, and she loves Christmas 'cause it's fun.
Really, she just likes the presents, and wants people to buy stuff for her and Lucas.
Call me odd, but as I see it, if you're not celebrating it for its religious significance, you shouldn't be celebrating it. It's insulting to those who actually practice the religion.
