"Clearly to you, but not so clearly to me," Remus said to her simply. "You forget, I am supposed to have lived in your past, Ginny, as have your mother-in-law and Sirius Black. Convenient, is it not? That we should not know anything about your life.
In that regard, I must ask you to pardon me if I feel the need to contradict your version of the future," he continued steadily. "You must understand how difficult it is for me to trust you right off. After all, Ginny, think about it. How would you feel if someone came strutting right in, claiming to be your grandson from a future you would probably never know about, the way you did?" He shrugged...for effect. "To even say that it is easy is an understatement."
