That wasn't really a clue! That's actually my name! "Not James".
I turned up at the finca one day by myself and apparently I look like a cat here called James. When the volunteers asked if I was James, Emma answered "It's not James.". After some confusion if I was, in fact, James or not, I became Not James.
I am very happy with my changed life here at the finca and I am glad that I chose this place to turn up at!
