Actually, if Paul were living with some mental health challenge, known to this co-worker, he would have a case. But put (perhaps a bit too) simply, calling someone what s/he isn't won't get you into nearly as much trouble as calling someone what s/he is.

Back on topic - I just remembered my first week working where I do now. I applied for the job in great part to swap a 15-mile car commute for a 1.5-mile bike/bus/walk commute. This was right at the turn of the century, before the prevalence of studded tires, etc. Pretty typical winter. Still in my 30s, I just rode a "stock" Univega hybrid, no special gear. Felt good to leave the car in the driveway every day. Most days I happened to push the bike out about the same time my next-door neighbor was leaving for work. We'd exchange g'mornings, etc and be on our way. Took 'til Friday the first week, he finally stopped and asked "What's wrong with your car?"
