Not many people can switch writing styles, their personal style will show through sooner or later. That's how you can tell larry root after reading his sock puppets.
I guarantee you I could pull it off if I wanted to, but then I wouldn't have the satisfaction of everyone seeing these losers getting humiliated with the hard factual evidence I ram down their throats under my username when they regurgitate their baseless pathological lying.
Edit: I hope your Dad is doing well.
