"Dear Fox,
I suppose I don't have anything else better to do, except write you back...
I don't mean to seem rude; however, I don't believe I recognize the alias "Fox". Nor do I remember ever using the alias "Raven".
So, if we have met, I don't believe I remember you.
Just curious, if you don't mind me asking, how did you know where I lived? Or that I had a welcome mat in front of the door to my house?
Are you some stalker or crazy neighbor?
No offense...
Your Friend, Raven"
