The most interesting thing is that even there are only few people who reply to your requests without hesitation, some kinds of feeling of being willing to help them back on some day occurred inside your heart. In face, I felt like I just swearing to help them back for certain on some another day.
Even for those I don’t really know well, I’ll still try to help them as much as I can.
(For sure, if it’s about money, I’ll spend more time to see how to help.)
What I understood from these feelings and thoughts is that it’s not really about “using or exploiting” friends. “Using or exploiting” is nothing more than expression.
