"It's a pleasure, Mark. I'm Bruce." He lets go of Mark's hand, straightening up. "There's nothing to apologize for. I don't feel accosted. I feel grateful, because you're right: having something to do will help. It'll give me something else to focus on besides," he gestures at their surroundings, "all of this and how weird it is to be here."
