Price tags always come off for us too - the only exception is when my Mom or sister buys an outfit or something that they found cute and on sale or whatever. We're so close and it's so familiar that it doesn't matter. In fact, we'll brag and be proud of ourselves for the great deal we got. BUT, any gift going out of our house, or giving on an occasion like birthday or Christmas the tag always comes off.
We do the picture thing too though, but our family is sort like picture crazy. We take pictures of everything all the time. We're pretty obnoxious about it actually. BUT, I was recently scanning a bunch of old pictures from my childhood and my dad's childhood and I wish there had been more. I have several of birthdays where I'm surrounded by wrapped packages and now I'm wondering ~~ what was in those packages - what did I get for my 4th birthday - what was I into? It would have been cool to have some of those pictures too.
At Christmas time, we ALWAYS take turns unwrapping gifts (and there are 27 of us!). It's never a chaotic free for all, paper flying mess. The kids go first (until they are old enough to wait their turn with the whole group) and they take turns, even at that age when taking turns is so hard and the presents are so exciting! It's a few hours, but everyone spent their time and money picking out gifts and we want to see what everyone got - appreciate it a little, y'know.
