I haven't mentioned bicycling at work much. I work for a very small company with only 11 employees. They do tend to know when I have a package with bicycle parts delivered to the office. Same goes for anything else I have shipped there.
I've been working there for 24 years. The strange thing is that back when I was a motorcyclist no one told me to be safe. One of them heard that I was bicycling and they told me how dangerous it can be. But none of them have been motorcyclists and all but one haven't ridden a bicycle since they were a kid.
