I live in an apartment building with an inner courtyard. One Sunday morning I woke up to the neighbours’ kid (aged five or six) standing in the middle of that very courtyard, SCREAMING his lungs out, calling for his mother, who was apparently still getting ready in their flat at that time.

As I went back to bed, with the angry screams only slightly muffled by the now closed windows, my mind went into problem-solving mode and this was one of the solutions it came up with. ;)
