The eternal struggle of group projects, visualized through the laws of physics! When two forces meet - your partner's complete inactivity and the normal force keeping everything balanced - something's gotta give. In this case, it's your sanity and grade. Newton's Third Law should've included a clause about academic freeloaders: "For every action, there is an equal and opposite reaction... except in group projects where one person does everything while the other mysteriously develops temporary paralysis of all productive abilities." The normal force might prevent objects from passing through each other, but it can't stop your partner from passing all responsibility onto you!
