Here is what I should have said to some recent acquaintances (who I likely will not see again):
It’s not all about you. Just because you think that the world belongs to you doesn’t make it so.
The animals of the Galapagos have plans of their own and they do not include showing off for you.
It is not possible to convince all the other people at the theater not to take pictures because they may momentarily block your view.
The airline did not ask me which seat I reserved for you. Nasty people- they just decided arbitrarily.
The Chinese guides were not spying on us; I promise you- they did not mistake you for anyone of consequence.
Just because you have an outdated, inaccurate guidebook in your hands, it does not make you an expert on a place you have never visited.
Taking food with your fingers and coughing and sneezing on the serving dish might account for your having spread your cold to the others who were not aware that the serving dish had turned into a petri dish.
Berating family members in public does not enhance your reputation.
Gratuitous criticism does not make you seem erudite; just crotchety and unpleasant.
Common courtesy is apparently not so common. Ditto common sense.
If there were a contest between “rich” and “kind”- kind would always win. I don’t admire you. I pity you.
And remember this: Beauty, money, and material things are fleeting, but good character lives on. There is still time to develop it. Try. It is a gift for yourself and for all those around you.
