Partner (male) thinks EVERYONE knows it's not ok to pee in the water. That it makes a horrible drum roll noise and no one wants to hear that. Having been married before I know not everyone feels this way... Not why I divorced him BTW 
Wondering what's the 'norm'....
Not just weird curiosity BTW, trying to settle a difference of opinion between father and son.... In a light hearted way obviously.
Is he being unreasonable to think peeing in the water is NOT ok? Let's have your votes ladies
