Gao Yang held a paper bag in each hand, with two hotdogs in each bag, so he couldn't eat them while holding them. He walked over to the homeless man he had noticed earlier and whispered, "Hey, brother, if you're hungry, I can treat you to two hotdogs."
The homeless man, head down, knees hugged to his chest with a piece of cardboard thrown at his feet, lifted his head and looked at Gao Yang in surprise. When he saw Gao Yang holding a hotdog right in front of him, he took the hotdog and nodded, "Thank you."
"You're welcome."
Gao Yang opened the paper bag and took out a hotdog, standing there gulping it down, and then realized the homeless man was eating much more voraciously than him.
"Oh, man, you look like you've been hungry for a long time."
