Correct. Friends are really required in life. I have read a poem in my school days. The meaning of that poem is when the water pond is full,many frogs will come. But when the tank get dried, all the frogs will run away. They never care about the pond. Likewise relatives may be coming to you when you have money and they require your services. But when they feel you are of no use, no relative will look at you. But a friend is different. He will help you when you are in difficulties. They share your joy as well as sorrow. So I agree that friends are like mirrors and best friends are like our shadows. Real friends will never leave a stone unturned to help you out from your problems. But you should be careful in selecting friends. Some people will be your friends to get their works done. Once it is over they may not even respond to your phone call. So choose a friend correctly. A friend in need is friend indeed.
