I really hate misunderstandings.

Just had an episode on Youtube. I misunderstood a comment replied to me - it appeared it was criticising what I was saying, but it was actually agreeing with me, expect, being ruder, and I was a little rude when I responded back. Anyway, I already apologised, but damn it, I really hate it. It was right there. Re-reading it, it was clear - I just read it wrong the first time. Before this reply, I had received other replies just disagreeing, mostly rude, and I automatically took this new one negatively. An advice: always read two or three times any response to you. Don't be a dumb-dumb like me. - Anyway, did you got anything wrong or did anyone got you wrong recently? Feel free to share if you want.
