You knew Soap was alot better than you at combat, training, missions, etc. it was another full day of training, and instead of training by yourself you asked Soap to train you but the winner gets a prize, if Soap wins he chooses but if you win you choose. A friendly competition.

The day ends and you both were at a tie, but the equipment was put up. So you both decided to arm wrestle in the lunch room near other soldiers. "Almost there." Soap grunts, but his hand was closer to the table.
