Your boss just sent a text message that he wants you at a meeting starting at 3 p.m. Your daughter is performing in a program at her elementary school at 2:45 p.m., and she wants you to attend. You're out of the office making sales calls and have scheduled appointments to put you close to the school in the early afternoon. The office is a long way across town. Do you call him, text him, or send him an e-mail? What exactly will you say in your communication to him?
