First,to make friends,you must be friendly to others.Smile at others and you are sure to get a smile in return.You should try to make a stranger feel at home wherever he happens to be.Think more of others than of yourself and never judge a person by his appearance and clothes.
Second,friends should negotiate instead of quarrel.
When you don’t agree someone,please discuss with him.
Finally,never believe in those who leave you when you are in trouble.And never leave your friend when he is in trouble.Remember,a friend in need is a friend indeed.
