Markham moved a little closer, his focus widening to include the other people in the park. He still wasn't okay with the girl, but it wasn't worth starting a fight with Abe (at the moment), and he knew someone would get his attention if he needed to be paying attention to the conversation. If Abe hadn't been so obviously set on being open and friendly, he would have asked if he was the only one who thought there was something off, but for now he would wait and see if some kind of reason presented itself. For all he knew, it was just the heat messing with him — there was certainly enough of it to go around.
