A fool may be known by six things :anger without cause, speech without profit, change without progress, enquiry without object, putting trust in a stranger, mistaking foes for friends.
A coin is easy to earn, a friend is hard to find. The coin depreciates but a friend appreciates. I lost a coin when I texted you, but it's okay because I got you.
When emotions play their role the heart cries.When heart cries it does not make any sound & the person who listens to that unmade soundis called a Friend.
