Smell v. Hear

I was in the bathroom this morning, and I asked Riley to come into the bathroom to brush his teeth. When Riley got to the bathroom, he told me that he could not brush his teeth because the smell in the bathroom was disgusting. I turned on the fan to air out the smell, and Riley turned off the fan because it was too loud. He tolerated the smell and brushed his teeth without the fan.

I think the smell was the lesser of the two evils with regards to his senses. He could tolerate the smell better than he could tolerate the sound of the fan.
