It has to be psychological and not texture because there are some foods that he eats that would have to have the same texture. He sees the food and automaticly associates it with being bad. I know I would be the same if someone were to put a plate of squid or octopus in front of me. I always say "I have enough food that I enjoy to not want to eat that shit" without even trying it. I was a real picky eater ( George Carlin - a big pain in the ass )as a kid but my taste buds developed as I got older. Sam just hasn't gotten to that stage yet oooooooooooooooooor may never.
