1: correctly set up a state of mind to treat each other correctly, don't treat each other as a child, regardless of age, to treat friends with sincerity, respect for the elderly, the children, love and care, but it is clear that you understand the relationship between the elderly and the children. No matter how old or small, you should treat your friends with the same sincerity as you would treat an elderly person with respect, a child with love and care, but you must clearly understand that we are all equal
2: About Payment In fact, this is out of their own will, honestly, others did not ask you to have to do to her how so we like and want to take care of others because of their own hearts and to act out of their own volition, so don't ask others to be grateful for anything. So don't ask others to be grateful to you, but according to the concrete performance after giving to summarize and evaluate this kind of giving whether it is worth it or not (personal opinion) In fact, when the relationship is good, we all want to give each other our hearts, livers, lungs, and when the relationship is not good, we feel that we have given to the dogs, but it is not necessary to do so, when the relationship is good, you will be willing to give, and feel contented, and when the relationship is not good, you will just let it go, and then you will have to give to the other. There's no need to be sad about it. What's done is done and can't be done again.
