Apologize to people when you make a mistake. Be a good listener to your friends. Your buddy might not need your advice or help solving their problem; they might need to talk and explain what is on their mind and troubling them.
Friends stick up for each other when they can; you might jump in and help a buddy who needs it, and your friends can help you when they can. Friends are good to each other, and that's why they are your buddies.
