I hope you don't mind, but I used you today.
Well, sort of.
I needed to return your call, but chose to do it just as Troublesome Co-Worker was approaching my desk.
As it went to your voicemail and he was still standing here looking at me, I covered the receiver and said sweetly, "Do you need something? It's going to be quite a while."
He said, "Um, muhm mumblity fumblity foom moom," and walked away.
I left you a message and made three other phone calls lest Co-Worker should think I was finished working.
I hope you don't mind,
All my love,
p.s. I really think I might be on to something. You may have more phone calls to look forward to over the next 26 days. Do you mind if I call you seven times per day?
