Good friends will always be miss. It might be because their teaching or maybe because they never felt the difficulty like their grandparents did.
Some people take advantage of other kindnesses. Like the one you did for me. I must repay you, I cannot take it for free. I will take a long time to repay but I will. That is what I am going to teach my daughter soon. If someone is being kind without ill intentions, the person deserves to be repay back with the kindness they give.

I have been living for 32 years in this world and it is my first time meeting someone like you.
