Marcus Aurelius explains it all to you:

“Don’t be irritated at people’s smell or bad breath. What’s the point? With that mouth, with those armpits, they’re going to produce that odor.

–But they have a brain! Can’t they figure it out? Can’t the recognize the problem?

So you have a brain as well. Good for you. Then use your logic to awaken his. Show him. Make him realize it. If he’ll listen, then you’ll have solved the problem. Without anger.”

The Meditations, trans. Gregory Hays (New York: Modern Library, 2002), 5:28 (p. 62).
