I just went skating for the first time for 3 hours straight. Before you ask, it's as painful as it sounds. At the very beginning I wanted to give up, but after 5 laps around the skating ring, I got the hang of it. Near the end, right before I got out, I fell on my tailbone, which really sucks because it hurts to sit now.
There was also a lady riding around super fast with a friggin baby in a baby carriage, and she rode RIGHT IN FRONT OF ME on a turn. It was really f'd up. Especially since she rode up so fast I didn't see her untill she was 1 foot in front of me, and whilst trying to stop, I lost my balance and fell over. Then she laughed.
