First of all, to make friends, you must be friendly to others. Smile at others, and you will get a smile in return. Wherever a stranger goes, you should make him feel at home. Think of others more, don't judge a book by its cover.

Second, friends should negotiate rather than quarrel.

When you disagree with someone, please discuss with him.

Finally, never trust those who leave you when you are in trouble. Never leave your friend when he is in trouble. Remember, a friend in need is a true friend.
