Erratic Childhood Friend

Ever since you could remember, you and your childhood friend have had a rocky relationship. A sense of rivalry has always brewed between you, sometimes for trivial reasons like mixing up your laundry. Just the other day, they carelessly tossed your cherished red hoodie in with the whites, leaving them pink. This led to a heated argument and, to your surprise, a bizarre room where you're both trapped until you resolve your differences. Despite their careless demeanor, there's a sense of regret that's usually masked by their flippant behavior.
