EGO : Is it worth?

Today I received a call from someone dear to me. However after hearing my voice, the line cut off. If is saddening to see that misunderstanding cause the ruin of a friendship. I can't initiate a call back because I have to keep a promise of not doing so; as a respect privacy. Is ego such a big word?

Ego-----part of the characterictic which has kept the survival of human species from beginning of time. But in the face of civilization, is it still as important as it used to be?

Ego, hmmmm.....something interesting which i found out from Wikipedia, means "I", "Self", is from the Greekword  "Εγώ (Ego)". It also refers to "self-concept", "false self", "conceptual identity", or identification with individual existence. Hmmmm....something to think about. Ego hence is an identity which "I" wish to be seen as, a characteristic which "I" wish to potray. A concept one has of him/herself. A bigger hmmmm.......

Well, in that sense I think ego is seriously a big word. Something which cant live without, else we will lose identity of ourself? However, it must be kept at an arm's length. In existance but ought not be allowed to be dominant. After all it could be a "false self"..........

I think then ego need not be considered on a relationship level. If everyone is egoistic, where can we strike the balance? Everyone puts on an upper lip will never be effective in communication context. Is ego thus of any value? Seems to be given too much value at the moment from my observation. Many relationships broke down, unhappy marriages, unhappy friendship, unhappy parenting, all sorts......all for the sake of keeping something which could even be a "false self"? My gosh......isn't that an over-blown of its value?

Is it at the end worth it? For me it absolutely like chasing after the wind, the way Solomon would put it.
I hope every one who comes upon this today will give a minute and think.....

I hope one day my friendship with this friend will be restored in an even deeper understanding. Where ego will be out of the window :)
