Tween angst

I have so much more empathy for my mother than I ever did before. I simply did not recognize that boys, too, go through the horrible, I mean, fun, tween stage. Being the oldest of 6, 5 of us being girls, I'm sure that we had more emotional outbursts than Justin has. He is still such a sweet boy, but he's now starting to say and do things that he never did before. And his body is starting to change. Yikes! My only brother was waaaaaaaaaaaay down the line at #5, so I wasn't living in the same house when he was going through all that. I don't know what to tell Justin so I tell him to talk to Kent.
I'm prepared to talk to Natalie about the joys of being a woman, of dealing with those monthly trials (before, during and after each cycle) and bras. Well, we're already talking bras because she is, and always has been, obsessed with my bras. (Ask Jennifer and Bailey DeTemple and anyone else who was near the Kohl's dressing room last year at this time... something about my "big, blue bra" coupled with hysterical giggling/laughter. I may have even posted about it.)
Boys, though, not so much. What changes do they go through? Do I really want/need to know? That's what dads are for, right? I have noticed that he's changing. He used to look like a boy, but now he's starting to look so much more mature. How is it possible that in 4 1/2 short months I will be the mother of a teenager? I'm too young!
