Why do women often have "challenging" mother-daughter relationships?

Today I was griping to a friend about my mom. I was saying that my mom often says certain things that annoy me and she said her mom says things that annoy her, too. Different things than my mom says, but annoying just the same. I told her that we bitch, but when our moms are gone, I know we’ll miss them and cry like babies. It got me thinking that women often have relationships with their moms where we get on each other’s nerves. I’m sure my mom gets annoyed at me, too, and likewise, I’m sure other moms get annoyed at their adult daughters.

I’m not saying all women, because I’m sure there are mothers and daughters that get along wonderfully. It just seems in general, there’s often friction. Not necessarily terrible, hateful stuff (although there can be a lot of that across the board with all relationships), just petty annoyances on both sides.

Why do you think it is that women often have annoying mother-daughter relationships?
