A good friend is someone who you know you can always count on, who will be there at your best but most importantly at your worse. This person is someone you can go to without being afraid of being judge. A great friend is someone who you know will always have your back and go down for you when you need it. A average friend might just be someone who you talk/hangout with once in a while. A great friend will also tell you what's wrong and right when you need it. A average friend will just tell you want you want to hear.
