I have known people who were what I call late people. Some liked making a grand entrance. They were selfish and enjoyed being noticed. For them, it would be unthinkable to not get an earlier start. Many were poor planners. Some did not care if they were late. They saw no problem with it. All were helped when my friends and I would just leave without them. Knowing we were no longer going to tolerate their lateness helped them to start earlier.
