I like happy because in happiness we feel joyful. we also respect other's feelings and talk to them while in anger or sadness its not possible. we speak good words when we are happy which others like and gives respect . it reflects our personality. it is like a ripple in water that are caused when we drop a pebble in water when we say a kind word ripples are generated by it which leads to more bigger ripples that is wave which spreads on and on and makes the other person happy.
