My boss has a hard time sitting still, so he got a treadmill with an attachment for his computer. He types emails while he’s walking, and he makes a lot of mistakes, but is too impatient to use spell check. His last email to me was illegible. I was in a mood, so I sent him back one that was just as illegible. He replied with, “It’s a go then.” I have no idea what I have agreed to.
