it is an essential part of my daily existence and is only gross if you proceed to eat the booger or wipe it someplace public
Saying that such a natural human function as picking your nose is gross is simply idiotic. It's on the same league as saying that trimming your nails, sneezing, yawning, brushing your hair, picking an eyelash out, and a dozed other activities are gross. People are ridiculous. Go out there and pick your nose with pride!
What else am I supposed to eat for dinner? I poop too...I suppose you people think that is gross too...pffft
I'd much rather pick my nose than be caught with a booger in plain view. Just wash your hands afterwards and it's all good.
It is all a matter of perspective, myself personally can find many natural human functions gross, i however don't consider myself idiotic.
