here's a story from a long time ago.
i was working as a housemother at a boarding school. not important which.
and it occurred to me to wonder how easy it was for the students to look into my bedroom window, so i went out on the fire escape ostensibly to clean the windows on the outside.
later that day one of the students came to offer me a homemade cleaning solution along with the subtle message: we know you were spying on us.
oh, how wrong he had been, but what could i say? "i was only checking to see how easy it is to spy on me"? because THAT would totally not have sent up any flags.
