When I told my brother to take a shower cause he stank. Keep in mind he had not showered for 6 days straight. He argued he didn't but I told him he's gone nose blind from smelling his own stink all day. Hee wouldn't know. So, to test it, he ended up taking a shower. Since he washed all of the stink off his body, he didn't actually smell how bad he was before he showered until went back into his room. He smelt his preshowered stank throughout his room and that's when he admitted that he was wrong.
