At around 1pm today, just before lunch, I entered into an internal debate.
"Does my car have a sunroof? I don't think it does"
"No wait, it probably does"
"I'm sure it doesn't"
"No, I'm positive that it doesn't"
"But surely it does"
This went on for a minute or so, during which I assured myself that no, it didn't have a sunroof. I went to look out of the window.
It does have a sunroof. Well I never!
Perhaps one day I will learn the difference between a sunroof and a moonroof. I imagine it is similar to the difference between a rainbow and a moonbow.
