In considerable people's views, what is the most important thing in our life is money, for it can give us anything what we want. However, can money really buy everything? In fact, it is not the case. The best things in life do not cost money such as parents' love and real friendship.
Our parents' selfless love is priceless and we do not spend money on it. Parents always consider their children and do anything as possible as they can for their children for no return. Even numerous parents can sacrifice their lives for their own children. In my opinion, it is not the money which can make parents do that. Even though you give huge amounts of money to a couple of parents, you still can't get the love they pay for their children, which is the thing they are willing to put in. It does not cost money.
A real friendship also does not need to cost money. The friendship is built on the similarities and the same interests. Besides, the sincerity in the friendship is vital. A real friend is the one who really tread you as a part of his/her life and always put you in his/her mind. Maybe you will say I still can make a person treat me well if I give him/her enough money but what you get just the labor you paid money for instead of friendship. What's more, a real friend lend you a favor to you, never expecting your repayment. He just hopes you can be happier. It does not need to cost money.
In a conclusion, the best things can't be balanced by money. Money can't buy them and they do not cost money. If we own these best things, we should treasure them.
