I’m a particular kind of pin. If I am stuck into the coat of a person, I will put that person to sleep. If I am removed from the coat, the sleeper will wake.

I’m not a jabbing pin, you see. I’m not a pin that goes in.

I can put you down painlessly. I slip in, ever so secretly. I don’t even get under your skin!
