No matter how bad people may seem, they possess at least one virtue. Be like the humming bird and pick out the sweetness of everyone's character.
Sid said -
“He that is thy friend indeed, He will help thee in thy need: If thou sorrow, he will weep; If thou wake, he cannot sleep: Thus of every grief in heart He with thee does bear a part. These are certain signs to know Faithful friend from flattering foe.”
P.S - Could readers please interpret it for especially the last two lines. :)
