Confession: I was a bit nervous about taking them by myself (my wife had to work). New things to learn don't always go well--especially if they involve falling down. Anders is still riding his bike with training wheels because he's fighting working towards taking them off. And right off the bat, as we were putting on our skates, Anders didn't want to do it anymore because the skates were too tight around his feet (they were the right size, but he wanted more space to move his feet around within the skates).
Surprisingly, Anders was the one who took off. I did a few laps holding on to each of their hands. But Anders starting going by himself. He believes he counted 17 laps around the rink before we left. Nils wasn't as fond of it (though a few hours after we'd left and were home, he wanted to go back and skate some more). And I got a good workout from holding Nils up and keeping him from falling.
