Meditations 5:28

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 they 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.
