That awkward moment when you're calmly picking your nose in the safety of your (or your parents) car, and then you turn and see someone spying on you, and looking disgusted.
I mean, it's not like they have never done it themselves....
A random fact: 44% of adults in a survey admitted to eating their own bogeys.
And I reckon the other part of the percent does it too, but just doesn't admit to it.XD
