Mr. Bauer is an amazing teacher at Archbishop Spalding, but it's difficult to communicate with him due to the deafness in his left ear. It's important for a student to be able to communicate effectively with their teacher, and he is no exception. 

Mr. Bauer, I promise that wearing a hearing aid doesn't make you old. Hearing aids exist to help those who are hearing impaired and there is no shame in needing to use them. In short, please wear your hearing aids so that your students can better communicate with you.
