I wore Ari's flip-flops for few seconds and my feet suddenly started to smell bad. I complained Ari that her flip-flops made my feet smelly but she argued that it is my feet, which made her flip-flops smelly but that didn't make any sense.

She wanted me to smell her feet saying that her non-smelly feet'd prove the fact that my feet made her flip-flops smelly. I smelled them carefully and objectively, and they did smell bad! I told her the truth but she did not acknowledge the 'truth' and tried to figure out who can more objectively smell her feet. I suggested Nora as a judge, for she can be very objective (although she apparently likes me a lot) but we soon realized that she wouldn't smell anyone's feet.
