Buttermilk

I was walking down Lincoln Road after lunch today. I overheard this kid, who was probably 8 and sitting outside Doraku, say, "Do you know what's odd about buttermilk..."
I must say that this was the coolest thing I've overheard in, perhaps, FOREVER. I always was fascinated by buttermilk as a kid. I mean, how can you not be?! It makes mashed potatoes and cake taste that much more delicious and all it is is buttery milk, and regular butter and milk are in mashed potatoes and cake anyway. Besides, butter is made of milk, but it's now butter/milk? There's much to consider about this substance.
Cheers to that little boy. Thank God for kids like that. Beautiful.
