“A true friend unbosoms freely, advises justly, assists readily, adventures boldly, takes all patiently, defends courageously, and continues a friend unchangeably.”

William Penn (1644–1718) ― Writer/Politician

This was a piece of literature that was frequently cited in the fraternity I was in during college—where many of my best friends came from. I think it’s a great reminder of what it means to be a good friend and can act as a sort of checklist on your own part in terms of the characteristics you need to exemplify toward your friends but also a reminder that your friends can provide you with these attributes.
