My son beat me at arm wrestling for the first time. He's up from 196 to 205, all of it muscle. He was noticeably more confident and mature in family discussions over the holidays. I even overheard him talk about a couple of girls whom he called "close acquaintances". Before, he would have called them just friends. He seems to hang out with baseball players, mostly. He's popular because he says he's got the best fake ID, but I hope he's just kidding me. In the fall baseball games which was the first time I got to see him since he went off to college, I could tell he was still physically maturing compared to the upperclassmen, but I think the difference will become marginal in the near future.
