Harley-Davidson - bringing out your inner jackass

I accompanied Dave to pick up a pair of (Harley-branded) boots he was buying from a guy today. Dave was on his Harley, and I was on my Aprilia. Dude actually asked, with me standing right there, "when is she going to graduate to a real bike?" I let him know on no uncertain terms that I can in fact drive a motorcycle and that he could pretty much bite me. Sometimes Dave is embarrassed by my behavior in public. This guy didn't even show up on his bike, he was in a Civic.
