Does a person choose his parents before he’s born?

My little boy doesn’t like peas. I explained to him that before he was born he was given a choice. He could choose to come into existence as a potted plant, a cup of decaf, or a little boy. He chose little boy. Then I further explained that he asked for parents who wouldn’t serve him peas. He was told there would be a long wait for that, at least 150 years. So he chose to come now anyway, and he needs to learn to live with the decisions he’s made. He didn’t seem to buy that.
