Irrational things that annoy you (and non irrational things too come to think of it)

[Tak]

Because I'm not religious?
Because it has nothing to do with "christ's birthday"?
Because even if religious people did use to celebrate it for that reason, its not that any more its just commercial?

I honestly don't know, and if someone wishes me a "merry christmas" or writes it in a card I won't snap at them or anything and will accept the gesture in which it is said/written/meant. It isn't something I get worked up over; I just prefer the other terms for it.
