Lazy hamster

A single point which someone hyper fixates so heavily on being wrong, they forget everything else ok with the whole.
Sometimes ultimately making the whole worse then it was, if the lazy hamster had been left alone.

I just remembered I forgot to colour in that one button on the characters shirt, I should go back.

What? No you’re painting was fine, just leave it. It’s not worth it.

No, no, the teacher’s going to be able to tell I’ll just go back and ask if I can get it.

Nah man don’t, it’s just a lazy hamster.
