Dear Lord, am I losing the plot?

I was driving past the common last night and in the darkness I saw a rat crossing the road! What should have happened is I was supposed to drive on by, wondering where it was going, what it was doing and why was it walking so slowly without purpose.

But oh no, instead I scream, slam on the breaks and sit there panting as if a fire breathing dragon was crossing the road!

Surely this kind of behaviour can’t be right.
