Be thankful it’s only pantyhose! I remember my sister telling a story her friend told her - my sister’s friend had two boys. One day (they were about 9 or 10 years old) she left them home while she went to the store.
In those days (more than 40 years ago) sanitary pads had loops at each end so you could hook them onto a type of belt. The boys took their mother being out of the house as an opportunity to explore her bedroom dresser and, of course, found a package of pads. They had no clue what they were, but, with their excellent imaginations, quickly decided that these things would make good masks for a game.
Imagine my sister’s friend’s horror when she returned from the store to find her sons playing in the street each with their toy guns and a sanitary pad across his face, with the loops around their ears!!
Pantyhose! No big deal!! A child’s imagination will suggest many uses for our everyday things that would never occur to us, and they will also lose interest in these items, sooner or later, without any harm to them.
