You walk into a restaurant and spot the people you’re meeting. You wave and head toward their table.
Someone is telling a story. Another person is laughing. You sit down and join the conversation.
A few minutes later, the door opens. You look up. Two people come in, speak to the host, and follow her toward the back.
You turn back to the conversation. Someone at the next table gets up. You notice. A server drops something near the kitchen. You look over.
Someone you’re with asks you a question.
“Sorry. What?”
They repeat it. You answer, and the conversation moves on.
A few minutes later, the door opens again.
You look up.
