Today, I became everything I hate in an e-mail response. I was typing a clarification email to a client (sent out to four people with me BCCed), and one of my interns stopped over at my cube to ask a question. Since he was patiently waiting, I quickly signed my name and hit send as I spun my chair around to give him my full attention. Out of the corner of my eye, I saw my computer pronounce "Sending to... The guy who you intended and EVERYONE ELSE".
I frantically tried to cancel the email, but my reflexes were simply not fast enough. The deed was done. My intern continued to explain the details of his question, but my mind was completely consumed with the fact that I'd just committed a HUGE faux paus.
