Thumb print behind gauge

A person is not OCD. They are not an Obsessive Compulsive Disorder, they are a human.

It's not funny to joke and laugh about OCDs.

There is no single OCD that someone has. You would not be annoyed by this because you have OCD. That's not the way it works. You do not have OCD, you have an OCD or multiple OCDs.

OCD is about obsessions or compulsions that interfere with your daily life. Cleanliness can be a trigger for OCD, but I doubt anyone in this thread has a diagnosed case of an OCD at all. Are you have intrusive thoughts when you see a finger print behind your dash glass? Do you want to bite your tongue off, pinch yourself, or punch through the dash glass to make it go away? I doubt it
