Indeed. I am able to separate critical and non-critical appointments, as I suppose most people can do. I am punctual to business meetings, class meeting times, doctor appointments, and such. I am perpetually tardy to things like going out to party, having a cup of coffee, or visiting a friend.

Being punctual is stressful, requires planning, forethought, and saying no to unforeseen circumstances. I can't imagine living being punctual in my non-business life. I would feel like a slave. I once lost a girlfriend because she was extremely uptight about punctuality and I wasn't. While that attitude might seem completely normal to an American, to me it was a glimpse into insanity.
