litmus test

here i am .. in my job place.. thinking what is really there in any relationshio thats keeps it going on or sometimes it loses the shine over the time..
So.. its the emotional investment that one has to make. but it is not vice-versa. I mean of you are putting a lot in it doesnt guarantee you will get a lot in return.
thats because- No two people think same thing at the same time.
Its as simple.. if you are As old saying.. its a litmus test if you are pure in the relation you will let it go..if its true it will come back to you..
but i say what the heck man… you cant let anoyone go out of ur life.. i mean anyone. its not about love only, its ur friens or new aquintances.. But it sure is hard to do. from now on i will be very particular about whom i include in my circle of trust.. out of sight is not out of mind here.
