“People use texting and e-mail for everything, but it’s not appropriate for somber situations. If you win an Oscar, tweet away, but if you’re talking about a death or an illness, you need to use more formal channels. For example: You can promote an employee via e-mail, but you can’t fire him. You can ask someone out by e-mail, but you can’t break up with her. Happy occasions can be casual. Sad or serious ones require a personal touch.”
