Handsome is as handsome does.
Expansion of Ideas School & College Section.
Everyone is attracted by a person endowed with good looks. But this does not mean that the person will behave as charmingly as his or her looks indicate. Handsome is as handsome does. The action of a person makes the person more attractive than he or she looks. People like Abraham Lincoln, Mahatma Gandhi or Mother Teresa would not have scored over others by the standards of conventional good looks, but they are remembered all over the world as people who glowed with an inner light of beauty.
We expect a handsome person to behave in a genteel way. We are pained and surprised when such a person turns out to be rude and mean. On the other hand, a person with plain, simple, ordinary looks can behave quite endearingly and you can learn to love and respect that person more than you would a stunningly attractive person. So, never judge a book by its cover, but by its content.
