Mana from Heaven?

Today, I was standing at our back door talking to Carson, who was a few feet away on the deck. We were having a great father and son moment. All of a sudden, out of nowhere, a pizza crust slams onto the deck right in between Carson and I. Befuddled, Carson picks it up and we both look around for the source. "Where did it come from?" I ask. Carson shrugs his shoulders, "I don't know, maybe one of the birds dropped it." I look up to see three seagulls flying away. "Here," Carson says, handing me the crust, "that's gross."
