75% chance

I teach a cooking class once a week to PreK kids. This past Tuesday, we made chocolate covered pretzels, using white chocolate. We had a lot leftover so I saved it in the bowl to make some more pretzels later. Later on that day, I washed my hands and dipped a finger in the chocolate, passing through the kitchen. I'm savoring the smooth chocolate in my mouth when I feel something a little thicker, that tastes a little salty. This should not be. I immediately pulled the thing out of my mouth- it was *definately* a booger. Seeing as though only 1 out of the 4 kids is mine, there is a 75% chance that not only did I eat some kids booger, but that it was from a kid who wasn't even mine.
