Ask this poem "Friendship among friends is also strong ..."

This is a Zen poem, should it be autographed? There is no specific source. As friends, (this person and I) have deep feelings, and if they can be transformed into flowing feelings, they can last for a long time; I want to be tolerant and honest with him, and don't live up to his friendship, because a friend of a gentleman is as light as water, and ordinary is really the most difficult truth to give up.
