A friendship scar

It's interesting how emotions can cross any physical distance and have their effect on humans.
I've been always obedient to friendship which is very valuable in life, however sometimes when I say what I think I hurt others' feelings.. problems is that doesn't matter if what I think was right or wrong, it always feels wrong to hurt others' feelings, especially friends, even if they are continents far from you! and what makes it even more complicated, is that even if you were wrong, sometime you hurt the other side so bad that he doesn't won't to listen to your apology, or even to let you realize that you were wrong and wish to change your mind!!
And you left bleeding with knife in your hand, you the one who hurt others, and for all that you are the one who's bleeding.. it's like fighting yourself, because you're human.. a human who makes mistakes.. and yet doing mistakes isn't enough to make you bleed, it's the well to excel and value friendship and fellowmen feelings which leaves unforgettable scars on your body. Only humans with scars are those who got into the battle, and exchanged theirs (and others) blood with booties, these booties are lesson of life, mine is; if I was that friend that got hurt, I would listen to what my friends have to say after they hurt me.. otherwise we'll both bleed to death!
