<i>Lynetta had on her usual pout, so that wasn't it. But my father's <u>idea of saying hello</u> was to lay into me about the lawn.</i><br/><br/><i>“No sweat,” I told him. “I'll do it tomorrow.”</i><br/><br/><i>All that got me was a scowl.</i><br/><br/>The speaker didn't mow the lawn so his father is scolding him at the dinner. Here "idea of saying hello" means ?
