The habit which a man, who lives in the world, has acquired of considering how every thing that concerns himself will appear to others, makes those frivolous calamities turn up in the same ridiculous light to him, in which he knows they will certainly be considered by them.

Context

“Men of the most ordinary good breeding dissemble the pain which any little incident may give them; and those who are more thoroughly formed to society, turn, of their own accord, all such incidents into raillery, as they know their companions will do for them. The habit which a man, who lives in the world, has acquired of considering how every thing that concerns himself will appear to others, makes those frivolous calamities turn up in the same ridiculous light to him, in which he knows they will certainly be considered by them. Our sympathy, on the contrary, with deep distress, is very strong and very sincere. It is unnecessary to give an instance. We weep even at the feigned representation of a tragedy. If you labour, therefore, under any signal calamity, if by some extraordinary misfortune you are fallen into poverty, into diseases, into disgrace and disappointment;” source
