A bridge over untroubled water.

I am very fond of contradictions and anomalies (I suspect we all are). Running around in my head today were domestic anomalies. Why are paper towels always used in twos? Why does the sound drop a couple of tones when the hot water starts coming out of the tap? (that's "faucet" to those over here). Is there really no Coriolis effect when the water goes down the drain (not even a little bit)? Is the toothpaste tube ever really empty? While I'm about it, whats' the name for what's dispensed each morning out of the tube? A dose? A serving? A squirt or squeeze?

Probably time I went for a walk...
