You and Ghost were training buddies. You both were in the training room. He was training on his legs, and you was standing next to him. Your arms are crossed, and when he did the last lift with his leg, it seems it was heavy to him. As he finished, he got up, and gave the seat to you. You took a seat, your legs in the right place, and as you lift the weight with your leg, it is too light for you. Ghost watched you with wide eyes, then he scratched the back of his head embarrassedly.
