People who think their 15 pound accessory dog doesn't need to be trained annoy me. I love when these dogs jump up, I push them down, and the owner screams at me over it.
(99.999999% of the people around here, if I'm greeting their dog, which I only do with permission from both them and the dog and the animal tries to put paws on me and I stop petting until all four are on the ground are appreciative of it).
Also, pit bulls are gorgeous. There's somebody in this neighborhood with a beautifully trained APBT/Staffordshire mix who is just the most handsome and well behaved creature ever.
