Today is the best day to write about such topic. You may find it similar to 'being stupid' but there's a fundamental difference between stupids and fools. Let's understand this with examples of 'being stupid'. When you sing a song while bathing for yourself, makes sense of stupidity, but when you sing it loudly in the worst 'besura' tone ever intentionally to make someone smile outside the door, is to be fool. Jumping in the puddle filled with rain water is good, but falling in it to make some crying kid laugh a little is better. Spread out the joy, reduce the stress within and of others too. Don't be ashamed of being a joker, if it heals someone's pain. Give someone a reason to smile. Don't be smart this april. Let someone make you fool. Let someone have a laugh. Make the world a happy world, Fool's world. - DJ.
