Although sharing something is supposed to be necessary for all social animals including Human Beings. It is found that animals also share with each other via different means. Sharing something works very similar to an opening in water dam, to maintain the water level of the dam. Sometime, you have to open the opening to lessen the pressure/level of the dam. Similarly, if we don’t share things, it can increase our temper level. It can mentally disturb. So to neutralize the build up pressure we have to lessen the level a little bit. So sharing is the best tool. I know that not all of you will agree with me but I am sure that mostly of you, WILL.
