After thinking for a while that he was unselfish and filled with the midos of someone Jewish, she began to distinguish between reality and what had been merely a wish.
It started when she sent him to buy gefite fish, but he came home with a potato knish. When she asked for a danish, he got her a piece of licorice. It seemed so amateurish to have such an obvious blemish.

My supply of ish words I did finish (it was pretty smallish, sorry more I couldn’t furnish), but maybe I’ll post more if I replenish.
