I noticed some boys skateboarding. They made it look easy and effortless, like sunfish sailing in the wind, except they weren't being driven by the wind, just moving by shifting their balance from side to side. They reminded me of birds, so smoothly did they soar.
I was filled with wistful envy, as I am whenever I see people performing with great skill, violinists perhaps, or dancers. I couldn't do something like that to save my life. It was all I could do to ride a bicycle as a child.
