Charlotte: [...] Is it ok if I go now?
Miranda: Sure. You want me to walk with you?
Charlotte: No. I just want to be alone, ok?
Miranda: Ok. But I'll walk a little way behind you, in case you change your mind and want to talk.
Charlotte: No, I'm ok.

Charlotte walked all the way home. And even though she never turned back, she knew Miranda was behind her.
