Whatever time estimate I give you, I will usually be later than that. Telling you I might be hours late for a 5pm meeting will probably end in me arriving at 9p

Whatever time estimate I give you, I will usually be later than that. Telling you I might be hours late for a 5pm meeting will probably end in me arriving at 9pm. That's why I find it best to have a reasonable time to aim for, and the people that know me know they will need to be able to accommodate my late arrival. And every once in a while, I might even be on time, though I do consider "5 minutes late" as "on time". Yes, the people that know me are nice and patient people. That's probably a major reason why I know them in the first place.
