Friends make identity?

I just watched an ad on tv from the new Samsung phone.

It begins as a really nice ad, about friends: close friends, working friends, boyfriends and girlfriends.
But then they claim that being connected with your friends, makes you who you are. Illustrated with a fingerprint.

Take a look:



What about it?
What about this: what's the deal with your friends creating your identity?
Is that true? Do those 450 friends on hyves/facebook/etc make you you? Are you better with 300 friends than with 50 friends? Are you a loser if you don't have a profile on a social media Web site at all?
Does that mean you don't have friends whatsoever?

Is it not so that it depends on your identity who become your friends?

Tell me what you think!
Are you also that struck by this ad, or don't you care?

Tell me!
