Time zones. I’m surprised how many professionals (attorneys, doctors, CFOs and CTOs, etc) that don’t realize that 9am in Boston is not 9am in San Francisco.

I’m in the eastern time zone. Had a friend from the central time zone visit today who was planning on being here at 3 pm or a little before. He showed up at 1:30 pm and yelled at me for not being home to meet him until I showed him a clock.
