Double Tap(s)

Filling the sink to wash dishes, I wonder why the water isn't getting warm. The hot tap is on. Weird.

Then I realize the cold tap is also open. Ah. Mystery solved.

But. 

Why would I turn on both taps? I wanted hot water; I wouldn't have purposely turned on the cold.

It was an odd thing for me to do.

The Husband found the story amusing when I told him about it later.

"If I'm doing stuff like this now, how will I know when I've really lost my marbles?"

So. Whenever one of us does something that makes us wonder if our mental faculties are slipping, we will ask, "Why would I turn on both taps?"
