Do you know who your father is?

It was when I put Valerie to bed one night that I understood what Tillie had been trying to tell me on the day I got my tonsils out.

"Tillie, how do you know if you're going to end up in heaven?"

"Well now, that all depends on who your father is."

I ask you my dear friends, do you know who your father is?
