My wife and I were out to eat. Since we had been shopping, I really had to go to the bathroom. I, of course, excused myself and walked down the short hallway in the back of the restaurant to the bathroom. And, horror of horrors, the door was closed.
I really had to go.
I waited, in pain, practically, jumping up and down as though that would help. Waiting, waiting, waiting... what were they doing in there?!?
Finally, I couldn't take it any longer and knocked on the door. No answer. I reached for the handle and twisted... and the door opened. No one was there.
Have you ever noticed how one dirty dish in the sink tends to attract others? Well, of course we think, the dishwasher is full. So, we'll just put them in the sink. Finally, someone bothers to open it and finds that it's empty, waiting for dirty dishes.
There are some sayings around "closed doors" and "waiting for open doors" but I don't think there are enough sayings telling us to "Open the damn door - it's not locked and it's not full. It's waiting for us to try it!"
