Why (squeak) in (squeak) the(squeak) hell....
would someone put shoes that squeak like a duck with every step on a toddler's feet, then take her to the library and let her run around?
It was enough to prompt several patrons to simultaneously hiss SHHHHHH at the very same time I asked through gritted teeth, "could you please pick her up? This was after security had already asked mom once to pick up the kid.
Furthermore, why would anyone buy those shoes in the first place? These, I believe, are the offending items.
