Your manager’s bad mood is weather. Don’t move into it.

Other people’s moods have causes you usually know nothing about, and almost none of them are you. When someone senior is short with everyone, the sensible reading is that something is going on in their day. Taking it personally means importing their afternoon into your evening, which helps neither of you.

Do your job, keep your answers even, and do not revise your opinion of yourself based on somebody’s tone at four in the afternoon. Check whether the same behavior is landing on everyone. If it is only you and it keeps happening, that is a different conversation worth having.
