Pretty self-explanatory. We all have NPC's we really have something to tell them. Here is one of mine:
Dear Emily,
Time after time I have had to come and rescue you and Mr. Floppy. I have about had enough. Why can't you be content to remain in the Westfall Brigade Encampment where you are safe? It's always all about you isn't it, Emily? The least you could do is have a little consideration for Mr. Floppy. Since you insist on wandering about, do the right thing and leave him behind. He is nothing more than an innocent victim. I know you will continue your selfish habits and I know that I will bail you once again but I want you to know, Emily, I think you are a stupid twit and I only do it for Mr. Floppy. The wolves can have you.
