Why does Tim think elroy never asked him why he was there?

Tim thinks Elroy never asked him why he was there because he sensed that Elroy understood the unspoken struggles and feelings Tim was grappling with. Elroy's silent presence and the way he treated Tim suggested a deep, intuitive understanding rather than a need for explicit communication. This allowed Tim to feel a sense of comfort and acceptance, making him believe that Elroy didn't need to pry into his thoughts to empathize with him.
