A wave of hand, a swift movement of wrist, mid-air, to take leave and bid adieu is the simplest and most natural development of human species among a wide range of expressions.
Along with a smile on lips or a joyful laugh, people express it by wide range of words and various name such as -Bye!, Tada!, Ta! Ta!, Adios! ....etc.
A mother stands in the balcony everyday and waves unflinching until her little one has traveled far enough to become invisible.
The pampered child, staring with sad eyes longing to go and be near his mother, is assured of her presence presenting a companion to share his agony brewing inside.
How beautifully a simple human expression carries a myriad of human emotions, isn't it?
