thank you for giving me water and giving me drink. we invite you to come down to the office whenever you would like to discuss any of these concerns further. sometimes you have to throw away the rule book and just do what you feel is right for your cat. adding a called shot on top of the damage die system makes it worst. so the only time we even have cause to think about our vision as such is when we think about a blind person who has no vision at all, or our own vision begins to fail us.
