I left my mom purse at home

Spritely young lady comes down looking for a safety pin or a needle and thread. She was wearing some funny, beret-type hat, the color of which I can't remember, even though she didn't leave but 30 seconds ago. In my mind's eye it was pink. I can't find a safety pin, but I finally locate one needle in a box full of keys and thread. I try fruitlessly to fish it out for about seven minutes, until I just dump the whole damn box on the desk. She's got a real sexy voice, not exactly sultry, more like adamantine or something, yet she throws me for a loop when she says, "I left my mom purse at home." Just what did she mean by that? I thought she was roughly 19.
