Loneliness is the biggest pain

Once there were 2 great friends. Both of them were very nice, helpful by nature. They both play, talk, and share many things with each other. But one day one more friend came into their group, another friend too was very nice helpful by nature. The friend mixed very well with both of them. Then one day one of the old friends due to some reason had to go away. All three friends were sad none among them were happy. But as it says what can anyone do the old friend left.

An old friend always hoped that his friends will always be there by his side but that didn't happen like that both the two friends were quite happy in their own life. Both the friends did not give any sort of attention to the left friend. The left friend did not feel nice but as time pass he understood and accepted what he was but one thing he always remember and said and so even understood that loneliness is the biggest sadness ...
