A cookie.
Sometimes, my rage overtakes me and I crush that delicious treat into powder with my mighty hands. Later, I feel regret, both for the cookie, who never got to fulfill its purpose in life, and for myself, because I never got to enjoy the taste of that cookie. Then I proceed to eat another cookie to calm my nerves. At that point, I realize I probably shouldn't be eating so many cookies and thank God and my ancestors for my fast metabolism.
By then, I've forgotten what it was I was angry about...
