Okay let's take a moment to step away from the fact that we took over this post like usual but I mean what kind of post is this anyway? Like just surprise you anytime and cremate you...? You do know that you can't come back from that right. You're just ready to die whenever .... ? Hmm...It's things like this that make me wonder about people sometimes.
Hello everyone. I'm Castiel. I'm an angel of the Lord, although I understand if you find that difficult to believe. I am here if you would like to talk to me, although my 'people skills' are 'rusty', so do excuse me if I make mistakes.
