Don't lose hope, eternity isn't over yet.
I like to think he'll return someday. I had an argument with him at the time as well and his rationale in it was poor, to say the least. And there were many others (Frink included) that were on my side in the argument. (Well it wasn't so much an argument as a disagreement. He was trying to be helpful, but then he just randomly through this one line in at the end of his post that ruined the whole rest of what he was trying to accomplish and I took offense to it.) Which makes me think that at the time he may have been going through difficult trials and not been thinking fully clearly. And to be fair, I was going through difficult times and not thinking clearly either, and my reaction to the things he said may have been over the top and I regret the way I responded, but I stand by the offense I took at the message, but I do forgive him for it.
And I'm far too lazy to drag up a link to this, sorry.
