Your late afternoon meeting scheduled for an hour has crept over the 75-minute mark with no clear end in sight. You know you still have a time-sensitive email to send off, and now you’re going to have to make the choice between leaving late or pulling out your laptop after dinner. On the outside, you’re polite, participating in discussion and responding thoughtfully to your coworker who is running the meeting. But on the inside, you’re annoyed. This person just took a giant step over your time boundaries.
