You ask about a little favor. Much less than you did for them in the past.
How do you feel? Giving a lot and not getting something little back, when you need them?
Of course, there are many exceptions. You do favors and you get it back much more.
You get things in return, which you did not expect at all.
Those selfish people who only take, will never find true happiness.
You will get it back, plus interest. From someone other than the person you helped.
It is true!
If you are selfish, take only credit, but don’t pay it back. You will be punished somehow.
