premise: And the hallway project I started on Saturday was waiting for its second coat of paint . So by 8:30 I 'd made many trips up and down the ladder and my arm could feel the effort ( partly because I ' m slow at cutting in the ceiling line freehand and partly because I ' m too much of a scaredy cat to get on the 3rd step of the ladder ! ) . After all the exertion , my stomach was a noisy grumbling complainer when I sat down to start my work day . And then it hit me ... second breakfast was in order ! What might be different if the narrator got to the 3rd step of the ladder ?
hypothesis: Their arm might not be feeling the effort
