Boy- There is no such thing as Santa, ask you Mom, she'll say its just her.
My L- No!!! Santa is real, not my Mom!
My R- Its not parents.
Boy- Well, how does he go around the whole world in one night? It really is the parents who do it!
Then I came around pretending I hadn't heard a word, smiled at the boys and said, "Hey boys, its time to go" Then L stands up and says, "Mom is Santa real?" I say, "Yes"
Then L turns to the boy and says, "HA, told ya!" and walked away with a smile.
So that answers that Q, R and L believe in Santa, continue the magic...
