wat u do 2 others come backs 2 u, or wat u do is wat u get! if u do gud 2 others same will come back 2 u n same wid da bad!

Answer 2

...That if you do somebody wrong, then supposedly someone will do you wrong in the future in return.  Sometimes it is true, because when you do something bad to someone, they might someday be in a position to help you out or not.  And if you did something bad to them, then they will remember and probably won't help you out.

Answer 3

it's karma, like if you do something good then something good will happen to you, same with bad.
