the best mirror is an old friend
many people think that new friends are better than old ones,because new friends can give them fresh feelings,quite on the country i don't think so.
i agree that new friengs will make you feel very intereseing in some place since you don't know each other a lot ,you have many topics to talk when chatting .but i pay more attention to old friend because the friengship has lasted long as the time goes,and you knew each other's heart for you are old friends.
moreover ,if you have difficulty in your life you may be shy to ask new friends for help since you don't know each other very well.but an old friend will be very helpful and willing to help you.
the most important thing is that old friend just like a mirror in your life.new friend will not tell you when they see your fault because they don;t want to be rude and try to behave as polite as they can to you .but an old friend will not care about that ,they will tell you if they saw you made mistake without afraid of you will be angry with them.and they will be so kind and true thus made you realise your mistakes and correct them.as tiam goes,you will be a more perfect man and your friendship will lasts long too.
all in all,an old friend is a great wealth to a person's life.
