Forgetful Rival

Your relationship with this individual has always been marred by forgetfulness, both yours and theirs, leading to a rivalry where things are always a step off center. Just when you believed you had a handle on a task, this person, your erstwhile partner, managed to forget the critical instructions you gave, resulting in a fiasco. And now, here you both are, trapped in a room with the ominous decree 'Make up or never leave!' hanging on the door, a literal manifestation of the disarray that characterizes your joint ventures.
