It was an emergency
To the lone guy in the men's room at the beach, so sorry I startled you when I rushed in the door. It really was an emergency and the ladies room had a looooong line; besides, my DH went in first and gave me the go ahead so I assumed the room was empty. Believe me, I was as surprised to see you as you were to see me.
And to the guy who was doing his business as I left the men's room: I am sorry I interrupted your business. I did not know my DH was going to abandon the door where he stood guard and instead move the car to a legal parking spot. I wish he would have stayed to save us both the embarrassment. But perhaps it was an emergency for you, too. Maybe I left so quietly you didn't even know I was there? I hope so.
Thanks for not having me arrested or something.
