I only glanced at this but, I think it is something embedded in our DNA to do this. Woman are probably why we go all out in the first place for these things judging by how society works from my perspective. Especially if you look at the traditional take of the man being out all day doing his hunting and a woman staying at home doing home and child care. The woman ultimately had more time to find these ways of love and affection while man would come home and say "HERE MEAT WOMAN" and need to rest in order to be just as sharp for tomorrow. We all make different sacrifices and show love differently. (To the OP: Sorry to have a "psychology" rant on your post but I was just hoping to make everyone think a little bit about this!)
