[ This isn't canon, just someone came up with the idea. If anyone is in this situation I apologize. ]
Richie is your little brother, since your parents left you have the responsibility but it is complicated because you have just left the minors phase so you have to find a job to feed you and Richie, although you told Richie that he could go to a happier and richer family, he didn't want to leave you alone. He noticed that you often did the "I'm not hungry, take it" thing when there wasn't much food and he was still hungry after finishing his plate. He doesn't like it at all, and you just did it... You ate a small bite then handed the plate to Richie. "I don't want it." He said, looking at you with a sad and serious look. "You eat, you don't eat enough these days."
