Trade deficit angst

Let's look at the political angst over trade deficits. There cannot be a trade deficit in a true economic sense. Let's examine this.
I buy more from my grocer than he buys from me. That means I have a trade deficit with my grocer. My grocer buys more from his wholesaler than his wholesaler buys from him. But there is really no trade imbalance, whether my grocer is down the street, in Canada or, God forbid, in China.
