Hi there [이름]! Thanks for always finding time to do your essay. Can make a difference in the world means \"change\". What changes could it bring? I hope you were able to get it. But don\'t worry, we can discuss this later in class. I am so happy that you are with Carolyn. ^_^ I\'m sure that you are really happy. Talk to you soon.
