The Duck (The obsession)

I was born a twin.
My sister had a little stuffed duck.
I used to steal it, when she cried I'd give it back.
When she died I kept it. I Still carry it around in my purse.
I also got obsessed with ducks, and started collecting them.
So people started calling me Ducky, and I liked it.
So, Thats the story behind the ducks.
