Is there an actual poll coming?
I worked with my brother for a summer and it almost destroyed our very close friendship. He's normally very laid back and fun, but I found out when he was my boss that he's nothing like that. As he's 3 years younger than I am, that was a little hard to get used to. We both wound up quitting when a slew of other things went wrong with the job, and just in the nick of time. Thankfully, we can joke about it now.
