I asked someone to call me today, and then wondered all day why she didn't. I also kept trying to figure out why our home line kept saying it was 'in use' when it wasn't. Did I forget to pay the bill.
I never put the two together.
Tonight, it dawned on me that this morning I heard the phone ring. I tried to pick up in our bedroom (no ringer and a two line phone with only one working line) and when I couldn't coordinate enough to get to the caller I just slammed down the phone and went back to sleep. It seems I didn't hang up. All day, our phone line has been giving busy signals because I was too much of an idiot to even REMEMBER the morning phone call or check that phone (because we don't use it!).
