Lateness

Is it desirable to be on-time? YES.  Should an intelligent person's estimation of any quantity, time included, become more accurate the more times the estimation is made? YES.  So why are people late?  It's because they are allowed to get away with it - there is no incentive to increase their time-keeping accuracy.  How many times have YOU in response to “sorry I'm late” said, “don't worry about it” etc. DON'T - you are encouraging this selfish antisocial behaviour and making it more likely that they will be late for me tomorrow!  Although at times I have gone into a bit of a rant at someone who's been late, or simply left after 5 mins of waiting (not always practical), it is often necessary to be a little bit more polite.  I have taken to saying, “perhaps you had a good reason”, and moving on.  And perhaps acting on behalf of karma at a later time.  I most definitely do not excuse it.
