Dumb people who pretend to be dumber.

Just that. Regular dumb people who pretend to be dumber than they already are to make you think maybe they are holding back something but really they are just that dumb. As a human regardless of your IQ we are all pretty dumb, theres no need to pretend.(with the exeption of work, where sadly you often get punished for being more competent than what is needed)

Anyways was wondering if anyone els has that thought or maybe I am being too critical of people who are just terrified of being seen as dumb.
