Eris.
I have been the guy with no watch, no schedule, and no concern for such things at all. I have been the one wandering in twenty minutes early, or thirty minutes late, all the time. (Actually, in my case, it was an hour either way, sometimes more.)
It was a long time ago. I changed. I changed for reasons. I found out that not caring about time was only emotionally beneficial to me in a narrow sense. I had fewer friends, did fewer things, and had less varied interests in life. I also didn’t much care for being given shit about being late. (I don’t think I have done that in this thread, either.) But there were tangible losses in my life experiences because I had no calendar. I missed out on things all the time, which, after the fact, I found I really wish I had made it to.
Now, it isn’t the case that I am a clock-watcher now. I am absurdly habitual in a lot of things, so I tend to arrive at regular events and places at profoundly regular times. (Within three or four minutes.) But that is because those things do have specific arrival times, and I have adjusted my habits so that my unscheduled life tends to leave me arriving at the early end of my natural bent. It makes it easier to deal with bosses, and such. But it isn’t the case that I watch the clock to do it. I just do the same stuff all the time, and the same stuff takes about the same time most days.
When I am actually late, even by a minute, folks at work assume I am sick, and not coming in, and will call in a few minutes to tell them that. They think that because it is that rare. I don’t even use my alarm clock. To accomplish your stated challenge, I would have to deliberately make myself late. I don’t think I could do it without a schedule. I would just default to my habitual behavior every time I didn’t check the clock, and that behavior makes me about fifteen to five minutes early to everything that has a starting time.
I am never in a hurry. I mentioned in several of my posts about theoretical meetings to which you were half an hour late, and you found me not there. It would be true, were we to be regular associates that this would happen. But if you assume in your mind that I was there precisely on time, tapped my toe, and timed your lateness to the legal twenty minute mark, and left in a huff, you were mistaken. I arrived about thirty minutes, or five minutes before the time we agreed. I read a book, and sat around for a long time. (That’s my measure, just a minute, a while, a long time) I was bored, I decided you weren’t coming, I left.
If it happened a lot, and I think it would, behavior modification consequences would affect our tendency to have meetings. We would make those meeting plans less often over time. After a few years, you would wonder, “What ever happened to old Tris? I never see him anymore.” And I would wonder the same. No angst, no ire, but a much diminished friendship.
The fact is that your OP is correct in its primary assumption. People who are on time are going to be rude to you fairly often. There has certainly been a lot of that in this thread. (Hey, it’s the pit, what do you expect?) People are going to assume that you have no concern for the value of their time, which you don’t. The fact that you have no concern for the value of your own time does not make any difference from their point of view, and you should try to understand that.
But, hell, let’s talk about this over a meal. Say, breakfast, or supper, maybe some day next month?
