how can we tell?

yeah same here, and also the one who would always be there for you and wont tolerate your mistakes and same time correct it for you, friends are those even though you guys are not with each other for a longer period of time still as if nothing happens, the bond is still there!!just like that, friends no matter how distant we are from each other!!

Well, I believe true friends will be there if you need them. They will try to help you, and support you. Of course, they will tell you what you've done wrong too. Friends should be concerning each other, and remind you when you have mistakes.

i think your answer was good. a friend is always there for you.

There's a quote that says, " Want to tell who you're true friends are? Screw up and see who's left!" I tried it and it works, now I found out who is treating me as a true friend and who really is a friend who is there for me whenever I need a friend. A friend who is closer to you more than a sister or a brother, a friend who is there for you to pick you up whenever you are down, that's a true friend! And yes there are lots of quality to be called a true friend, but the important thing is you are a true friend to somebody as well.
