I came home this evening to find that I had a round booger hanging out near the entrance to my right nostril. I have no idea how long it had been there but I know for sure I had it while I was commuting home and most likely for several hours at work.
If it had been resting against the surface of my nostril it might have not been noticed but as luck would have it, the booger had managed to balance itself on the end of a nose hair, making it quite visible.
If it were only socially acceptable to pick your nose at work, I would not have had this problem today.
