Not having the
time to take a shit all day even though you know you have to. Or if there is not a place to take a shit.
When you are on a first date and you know you can't excuse yourself to take the kids to the pool.
When you are riding with your
boss all day and know you can't ask your
boss to pull over so you can have a shit.
On your first day at the new office when you can't ask the receptionist or your new
boss where the bathroom is only to be gone for 20 minutes dropping the bomb.
