Getting back to grandmothers. It's a topic that really goes a long way and mine is an enigma in a housecoat. The math never works out for her when she goes shopping. She’s always complaining that they gave her the wrong change, but she runs rings around any of us at Sudoku, let alone chess. In the first thirty minutes of the game, you ask yourself, “Where's my queen?” And she just looks at you, flashing a Machiavellian smile, and signals you to just make your move.

She also has her slips, of course. Not a single day goes by without her asking for her glasses. The conversation always goes like this:

- Have you seen my glasses, sweetheart?

- Which ones, Granny? The sunglasses or the other ones?

- Do I have sunglasses? Really? Never mind — I don’t know where I put them either. Would you mind getting both for me?

Smart, right? First she asks for something. Then she puts on a face like she’s puzzled, and finally, you end up looking for it. She’s such a strategist. She should be in textbooks.
