How does your family decide who opens their gifts first?

We go by youngest to oldest. I used to be one of the youngest but I"m somewhere towards the middle now. I remember being I think 7/8 and they tried switching the order one year so the oldest would go first. I was so mad I stormed out of the living room where everyone was and pouted in the kitchen. I was crying, huffing and puffing about it in a corner by the stove. Needless to say they never tried switching the order again.
