red flag or no?!

so i was in my bfs car and he was on the phone with our friend and he was trying to hear her. and i accidentally turned up the volume in his car while trying to turn it down, and he yelled my name and he was very annoyed. it honestly made me feel horrible and sad and i haven’t brought this up to him. Is this a red flag? I’m pretty sure he thought i did it on purpose. But still.
