Why is that people always tend to forget gratitude? They are so sefish till they get their jobs done..?

Answer 1

BECASUE, IT WAS NEVER BEEN TAUGHT BY THEIR PARENTS!

If some one do some good for a child, that child shall be guided to say thanks in a more-felt way!

At the same time, the parents in advance, should have been a role-model to the children, in praising the people who did some good for the family! The parent by themselves be grateful for the special people who have contributed "some good things" for them!
Seeing the parental attitude and their gratefulness towards others, children by themselves learn the habit of showing gratitude for those who have specially helped them in their Life!!

AND PEOPLE'S ATTITUDE IS NOWADYAS PURELY MATERIALSITIC AND THEY WILL FORGET ANY GREAT HELP THE NEXT MOMENT, INSTANTENOUSLY!!

But, you know one thing, what they sowed only will be reaped in the future, and thus will return for them sooner!!

Moreover, they would not get again the needed help from any people.
Because,
THE MESSAGE OF THEIR UNGRATEFUL ATTITUDE WILL BE INSCRIBED IN THE COSMIC RECORDS invisibly, and they will shortly fall from the top!

So, never to worry!

AND ONE THING FOR YOU TOO!

Here, in Tamil Nadu/ India the great leader EVR Periyar once said a golden word thus:

"GRATITUDE IS AN ATTITUDE SHALL BE SHOWN BY THE ONE WHO GOT BENEFITTED!!
AND IT SHALL NOT BE EXPECTED FROM THE SIDE OF ONE, WHO HAD SO HELPED!!

IF SO EXPECTING, IT IS NOTHING BUT 'PETTY MINDEDNESS' ONLY"!

So, expect not any Gratitude
from the "non-human beings" and
perform your duties,
if you so desired!

Expectation only gives you the pain!!

DO ANY THING,

but,

WITHOUT HARMING YOURSELF!!
