This troper had many kittens from the same litter. She was favouring one which was hers and really hated the other which belonged to the sister she was often quarrelling with. Whenever this kitty came for cuddles she just shushed him, pushed him away or ignored him. One day she heard in school that one of her kittens was run over by car, particularly the scrappy one. She said 'oh well' as she didn't care much. But on her way back home she saw the body...it was indeed the cat..
its head smashed. She cried for whole week and this changed her attitude towards people she didn't like.
