Do you have a way of making sure you did not leave the stove on?

I left the stove on twice today. Once the tea pot was on it (it’s an electric stove) and the tea pot got very hot. It was only on for about ten minutes, empty. The second time I had made eggs and the pan with some butter was left on (again, for about ten minutes before I smelled it).

This never happens to me, and so I was thinking I must be distracted about something. I also have my period, so maybe it’s making me a little extra air-headed.

I know some people are obsessive about checking the stove to make sure it was not left on. Do you have any method of making sure you did not leave the stove on?
