Hillary Rodham Clinton coming to TIFF industry conference to present docuseries

This spring, I adopted a three-month-old rescued German Shepherd mix. To say she is easily excitable is an understatement.

It is not really her fault. A puppy’s frontal cortex, the part of the brain that helps with decision-making and impulse control, is still developing. When an older dog, or a human, gets tired, we generally understand we should rest. Puppies have not quite figured that out. They often interpret tiredness as a signal something is wrong, which makes them more alert, more reactive and harder to settle.

That creates a feedback loop. The puppy gets tired, which makes her frantic, which makes her more tired, which makes her even more frantic. Eventually, this becomes what people call the “zoomies”: frantic sprinting, biting, jumping and general chaos.

From the outside, it looks like the puppy has too much energy. In reality, the opposite is true. The zoomies are not a sign of excess energy. They are a sign the puppy is overtired and does not know it yet.

DEAR MISS LONELYHEARTS: I just ran into my former husband with his new woman. It was a shock. She looked nothing like me — not nearly as good. In fact, she’s the opposite of me — red-haired, freckled, tall and skinny like a rake. I’m short, dark, with golden skin from my Italian background. That was what my husband used to say he loved in a woman.

Does that mean he lied — that he really didn’t like my looks and secretly longed for the opposite? That seems crazy to me. But I should mention that in our last miserable years together he didn’t even want to hold me in his arms and look at me. He sometimes slept at his office (or so he said) because he was “too tired to drive home.”

He could have been elsewhere — like in some other woman’s home — because he always used his cellphone to call me, not his office line.

How can I forget about the man I loved so much and finally move on?
