Answer:
The answer is: FALSE.
Explanation:
You should address. your principal in this case, as "usted" that's how we do it with more respect. This is often confused because in English we only have the pronoun you to refert to both "Tú" or "Usted", however, it is important to remark the difference when we speak in Spanish, as always, when addressing or greeting someone else, perhaps a higher authority, older person, etc... we might want to use "usted" rather than "tú".
