This is, of course, involving diapers and/or infantilism.
This might not be very dangerous to some people, but my most harrowing situation involved moving from my bedroom to the bathroom in order to clean up. Thing is, both rooms are located adjacent to my sister's room, whose door was open. It was at night but she was probably awake and texting someone while I was doing all this. As far as I know she heard nothing.
This could turn into a "close call" thread, but my intention is to see what situation you put yourself in that could have EASILY gotten you caught, but in which you received no attention.
