Well it depends, I have to admit I had done some stupid stuff too, most people would not trust me when it comes to rules, but then again...I only know just a little just to save my sorry little hide if a rule lawyer can manage to live through that then they are set.
My friend thinks everytime I do something wrong that is not in the rules he always has to ruin some plan I had set for reason, and he is a player not a DM he tends to suck up to the DM more then anyone who thinks he just the best rulelawyer yet, he said he was helping me, but then again he helps the DM more then he helps me when it comes it becomes difficult by what the hell he was thinking when he disagrees on actions I do for a good reason he has to make such an issue about it when he explains to the DM "This rules said..." Bla Bla Bla sometimes that it got me killed thats not the right thing to do to another player.
