Sacred Haven of Debauchery

Oh no - he misinterpreted what Mom said.
She asked me to finish the repairs in her
room, which is why I wasn't planning on
playing Heroes until January. I planned to
take care of things in real life first. But he
presented it as if Mom had ORDERED me: "Turn off the computer and go work – it's time for work, not for fun." He portrayed me as some kind of
grown-up baby, whose mom forbids him from
drinking, smoking, and sitting in front of the
TV/computer after midnight.

Well, that's a bit much! His only offense is that he made fun of your age. And I have to agree that it's a bit ironic, although not terrible. It's just that the usual internet restrictions for someone your age are different. But that's not the point. Everything else, about "ordered" and so on, you wrote yourself; I can't find anything like that anywhere. All I saw was irony. I'm not arguing; if you take it to heart, it might be a little offensive, but it's usually best to respond with irony. And in general, Heroist is a very nice person; it's strange that you managed to argue with him.
As for the rest... Maybe you're right about something, I have to say that it looked different from the outside, but let it go. I suggest that instead of analyzing "who offended whom and when" and making fruitless attempts to figure out where the truth lies, we just continue doing what we're here for: your set. If you can, send a link, and I'll try to comment on it.
