My students are used to my bike being by my desk. I have a few who ask a lot of questions. One of the kid's brother came in to look at my bike and asked me if he could pick it up to see how light it was! Then he told his brother that I was crazy when he found out where I live (it's 14 miles)!
Actually, the boys are more interested. The girls ask how I get my clothes to school and do my make up...
