Otto, by now, had had enough of a cool down period so that he was still angry, but able to express more than just hatred. He stopped, causing his friend to bump into him before realizing what was going on. "Look, I'm sorry," It was a quiet, embarrassed apology. "I just...I cannot stand humans." And after forcing himself to spend over an hour in a city full of them, his nerves were shot, and the extra excitements didn't help any. "No no, Otto, it's fine. I understand, don't worry about it." While he was genuine in saying that, it did hurt to be reminded of his incident, and that he still hadn't found any of his friends from the house. It made him worry, whenever he thought of it.
