Sam looked around and realized that he didn't have much choice. He didn't know what the girl had done to him, but he figured that sticking with her might give him the chance to get her to undo it. Besides, maybe she had a ball or something that he could play with.
Where did that thought come from? Sam let out a little 'yip' of agreement and then followed Maxine onto the bus.
He didn't notice the time passing all that much through the day. His emotions were simpler, and he kept getting distracted by various things. Following the scent of food to the cafeteria. Wanting to chase after various toys and sometimes his own tail. Making sure that Maxine had a constant companion. He felt very protective over her and anyone who didn't smell right would get snarled at.
