I am someone who doesn't care if someone doesn't buy me a present on my birthday. I don't care if my girlfriend proposes that we not do anything on Valentine's Day and maybe go out another time. It doesn't have to be February 14th that we celebrate it, or even the month of February, I don't really care. I don't need to have a Christmas tree to celebrate Christmas.
I'm also not very materialistic. I don't want anything for Christmas, and I perceive almost everything people buy me as useless.
Just to make things clear, I am not anti-holiday. I am basically the opposite of the girl who cries because her boyfriend gave her just chocolate on Valentine's Day but didn't offer to go out somewhere to celebrate.
Is there a word that describes my attitude and personality?
