Thanks Prag- I guess that was kinda rude of him too since my classmates get a timestamp and record of what I did wrong before I even knew I fucked up X,D
Iris - considering he just mad a snarky comment about it instead of reaching out and talking to you, I would guess he's just being an ahole and it didn't really affect him all that much. I think you're fine.
We all say and do stupid things, all the time, in life. What matters is when you do make a mistake, what is your response? You didn't mean to offend him, if he even is offended, and you sent an email to apologize. That's about all you can do.
