Last week I went on a field trip with my niece Tori's 3rd-grade class. Rollerskating! I haven't been rollerskating since I was 13 or 14 years old. It was a hoot! It took me a bit to get used to the skates but then I did OK. Had a couple of falls -- see bruise on knee at right (about 2.5 inches or 6 cm). Until I figured out how to make turns I'd skate all the way down one side, skate into the wall, turn, skate to the next turn, repeat. It was all quite comical.
Tori and I had a great time. She is much braver than I am. She wore inline skates. I opted for the more stable, four-wheel option. She's also a great skater! She can almost do the splits while skating. I didn't try that. I would have deserved whatever injury I received at that point.
