Basically, you originally had a post insulting the post above you, aimed at his bad luck brian meme regarding bonus xp weekend in regards to summoning xp boost. Now normally that wouldn't be a problem but the particular way you phrased your insult used both wrong information and rudeness. I then approached you on msn and explained that in the first bonus xp weekend, summoning was in fact boosted by the regular boost; however, you responded to me somewhat rudely (not that badly though, considering I was a banned member telling you how to be nice to people). You then said that you didn't care at all, but when I latter checked you changed it to what is currently in the post. I guess in hindsight my memory made the situation worse than it actually was but w/e, sorry about that. I guess it's no big deal but I still feel it was a bit mean.
