Being a consultant, I'm frequently changing where I'm physically working. A few months ago I showed up for the second day of a new assignment. The temps were in the single digits and there was plenty of snow on the ground. I locked my bike to a light pole (no rack available) and walked to the door of the building. A guy working inside saw me coming, didn't recognize me and met me at the door. It took me a minute to convince him I wasn't a homeless guy trying to get inside and that I was actually contracted to work there.

I thought it was funny. Every day after that when I'd see him I'd say, "the homeless guy is here!"

I don't worry too much what people think. People who matter don't care, and people who care don't matter.
