You'd get on well with my dog Phoebe. She has very firm ideas about postmen and how they should be barked off the planet if at all possible!
I thought I had arachnophobia, but as an expert at Exmoor zoo pointed out, if I really did have arachnophobia I would not have stayed in the same room as him and the tarantula that he was holding. I guess that what I have is just a strong aversion therefore.
