I agree with you Gabriela, whoever that girl was needs to be careful.
Obviously, John Lennon was one those incredible people that doesn't come along very often, and he's affected us all. But maybe you all need to read more of the things he's said. We DON'T know him. His songs affect us, and his messages are incredibly valuable, but that doesn't make him "ours." He was a real person - how would you like someone to talk about you that way? I'm not being judgmental, because John Lennon means a lot to me too, I'm just saying that maybe we should put it in perspective, I guess. Follow what he says, if it speaks to you, believe in what he says, RESPECT him, because he deserves it - but don't claim him. He is his own person.
