Differences. People change and lie all the time. Appearances can be very deceptive. One may not act in the same way in front of you as they do in front of others. But please, why be so rude? Not even to that girl, but to her friends who have done nothing to bring you any harm. You led her on, maybe with or without intention - but she doesn't care about any of that any more. You used her feelings against her, her abilities and skills - yet still, she left without saying a word. She even made an attempt to talk to you on her very last day, to talk without any regrets. To talk with a smile like she used to when she was deceived. That was in her past, and she intends to move on. She may realise all this and yet say nothing, because although she was the victim, she was not a fool. She knows. She may not have been hurt completely, but others will. So she wishes that person to be able to change themselves and be the best they could be - without making use of others.
