In my day to day life I have one that I struggle with everyday. My Fiance and I share a rental house with one bathroom.
Her and I have completely synched up poop cycles. It is weird. Like, it is down to a tee. Eating out at restaurants is even hard because one of us needs to stay back to watch the purse coats, whatever. My brain doesn't even seem to register sometimes that I have to poop until the second she heads to the bathroom.
Not only that, but it just happens that each time is also an emergency. So what is my game? If I feel the slightest sensation to poo , sprint towards the bathroom NOW.
Then I hear her from the other room. "You aren't going to the bathroom are you?"
Hell yes I am.
And I won.
