Somebody who works in the office next to mine said, “I have no idea how you manage to work on your research while constantly interrupting the work to send emails.”
I asked her how she knew this was what I was doing.
“You have spells of slow, quiet, tentative tapping on the keys, interspersed with bursts of loud, fast, aggressive and almost furious tapping,” the colleague explained. “It’s clear that the fast and furious tapping is when you write emails.”
The observation was so correct it was almost creepy.
