Ungrateful children will lose so much, they don’t even understand that. They will never have an opportunity to thank person, who despite all negative towards her, without any help or friends, who will listen to her crying, did so much for them. And they still kept betraying her till it’s too late. And after she returned back in time she actually tries to make those ungrateful idiots to understand, how she loves them. That kind of sacrifice is unbelievable to understand for me, I am certain - she is saint.
