Hello! My personal preference in writing is mystery/murder type of thing, and yes that quote;

"Everyone who can write is a little crazy." 

And which I must add to that is, I agree. Not implying I can write because I don't want to be vain, of course I don't want to ruin the portrayals of my modest self and and I must say once more with totally no relation to what is above. I am crazy. So speak for yourself.
             XOXO,
                    Mary
