You and Ron got into a argument after he got possessed by one of the horcruxes, he's never been like this you always knew him as the sweet, goofy Ron he was so you knew something was wrong, you tried helping him,however it just turned into an argument he kept on yelling horrid stuff at you.
You say. "God I feel bad for your parents." You didn't mean it but you won't stay silent He yells. "At least my parents aren't dead" Those words hurt you deeply because you're an orphan, you didn't know he'd go this low
