totally excusable for a person new to riding a bike.
when I was living in LA I went to InCycle in Pasadena to look at stuff I couldn't afford and there was a guy in the parking lot pulling up in his bike (nice road bike), fit cyclist, full club/team kit....helmet backwards. i thought it must have been a joke or a prank. I didn't know what to say so i just went inside and pretended I didnt see it.
