My granddaughter was turning two.  My daughter asked my grandson what he thought his younger sister would like for a birthday present.  Without hesitating, he said:  “I think she would like a plastic penis!”   I have a friend who was raised in a traditional Italian family.  My friend used to complain that her parents never listened to her but they ALWAYS listened when her older brother spoke.  I told her to get a plastic penis and put in on the table.  I told her I could not guarantee that they would listen, but that I bet it would get their attention.
