I cut an avocado in half and give one half to the visitor; and I carefully scoop the avocado gently, gently with a teaspoon (the Aztec records show this is, ahem! the fertility fruit) and I savor each scoop and eat like a pig (ah well, like a graceful pig); and at last I have the skin left in the palm of my hand and it’s tough and shaped like a boat; and it has rained and there’s a puddle of water on the lawn and an ant that’s been irritating me wandering about on my naked foot and I put the ant in the avocado boat and I set the boat in the puddle and I give it a gentle push and I say: “Bon voyage, Monsieur!” And then I look at my visitor, and that silly guy is still staring at his half and I ask, ever gently, “Do you need help with your fertility fruit there?” The visitor replies, “No" – and I wonder if I should get him brain food or perhaps set him off on another avocado boat…
