So one of my co-workers, Patrick, was out sick yesterday. I welcomed him back today with a one-word email, which I knew he would appreciate. It simply said, "Faker."
Not 30 seconds later, he responded as efficiently with one word to me, "Bitch."
I never use this word, but this is the only way I could explain my reaction - guffaw. I literally guffawed loudly. You gotta love efficient communication that can create a great belly laugh.
