how could one tell the true friends from false?

We're in an open system really. Every component interacts with everything around them and hand in hand with needs and outputs. There's always that necessity for someone to get something back from others since that's natural. Even charitable works get that gratifying feeling after helping out people so its not basically not a one sided relationship. Now when it comes to friends, you'll find true friends when they initially do efforts and favors even if you don't ask them for it. It might either have an alternative motive or that friend is merely building up a relationship wherein he or she could remind you of that kind gesture when the time comes when he or she needs a favor from you. Its typical. Anyway, friends do nice things to others out of concern and not from building enough inventory of gratitude. They are satisfied and gratified from the mere act of doing nice gestures to friends 'cause at the back of their minds or as well as in their hearts, they know that his or her friend would do the same kind effort even if he or she doesn't asks to. There are a lot kinds of friends and true ones are established from time.

Yes for sure cause you can feel it and U can tell wehn there is good or bad vibes and u can see it in there eyes... when your in a groups Like I am ... you know and Lisen to so u can realy see true color even when your eyes are not there

I think it is very hard these days to tell who your true friends are, people are so weak with the influences in life they can turn so easily this has happened to me and i am afraid i don't trust 100% anymore in any one....sad world today i think.
