TOOTHPASTE

And it burns, not a lemon or tomato burn, much more like sticking your hand in ice too long. That's not the point, the point is it burned like a mother fucker as it ran through my teeth and mouth and over bitten lip and cheek.
It burned on my tender tongue, bitten in anger. It burned and relief came over me as I spit it out, that damned Listerine toothpaste.
