Pee sounds

[Maunsell 26]

When my wife was working she said that she was near the toilets in the female staff area when one of her colleagues came rushing in saying that she was bursting and actually apologising that she was going to be noisy, she rushed into one of the cubicles as was soon peeing making a terrific hissing and splashing noise. My wife said she had never heard that before a woman actually apologising for being noisy.

 She also said that it was not unusual for colleagues if they were chatting to go into adjacent cubicles and continue chatting while they were weeing, again I didn’t realise that happened.

Nice your wife shared that with you. Yes it’s common for ladies to talk while peeing. Ladies even will share toilets on nights out so carrying on a conversation from 2 stalls is more common than you might think. 
The sound of a lady peeing is a big part of my interest and I like searching for pee audio online. I actually found a recording of 2 ladies peeing and continuing their conversation.
