I had that once, some kid ran.. no sprinted out of his house and half way down the sidewalk to give me the wheelie sign. No thank you.
Another time some young girls were walking and did something to indicate to Erik and I they wanted to ride. I told Erik the next time someone does that I'm stopping. I bet they shit their pants when they see I'm a girl!
But I like waving to the little ones that are just totally fascinated because it's a bike and goes "vroom, vroom".
