I wondered if I was a bit unusual?

Someone asked me recently (an ex marketing director of another company) what I did.
"Software engineer" I said.
"Ah, dark rooms, lots of cola and late nights!" he said.
"Er, actually I sit by the window, drink Earl Grey and try to get away at 5" I replied.
He gave me a sideways look and disbelieving expression that said "Yeah, right!".

Do you think you fit this stereotype?
