A co-worker stopped me in the hall to ask if I'm on a different bike today, because as he said "I usually see you on a mountain bike"! I haven't used a mountain bike since a couple of weeks in 2010, but I just rolled with it saying I had several and taking the opportunity to bore him with some bike talk

Mistaken identity since I've taken to commuting in my work clothes lately in this cool weather, and he probably doesn't even recognize me with my usual roadie garb. It's just funny to think about, that I'm incognito on the bike most of the time.
