I have a special water bottle that I use almost daily and for some reason the sound of filling said water bottle instantly makes me want to pee. I fill waters for the kids or in other bottles without the same reaction. I fill my special water bottle in different dispensers without the reaction.
It is some combination of our fridge dispenser, the shape of this bottle and the sound it makes that is such a reaction almost without fail I don't get to fill it all the way up before running to the bathroom.
I am somehow afraid this sound will be honed in on and used as kryptonite against me at some distant point in the future.
