Does the friendship between friends need a long speech?

A hedge between keeps friendship green. Between friends, friendship does not need a long speech. A true friend doesn't need you to say so many words of thanks. All he needs is a smile, a look, an encouragement and even a glass of water. This is a true friend. I remember a classmate named Li Quan. When I was most helpless, he gave me the card and told me that there was just enough money in the password to tell him. I didn't invite him to eat a meal and drink a glass of water, such a friend and such a friendship. Tell me, is it sincere enough? Did he give a long speech?
