Slips are slips. It’s not a matter of “oh look at me with my 10 years of experience in mafia! I can’t make a single mistake!”
I will take slips for what they are. If you can’t defend your action and have to jump to using your experience and berate me for being a novice player, this only shows that you are running out of arguments and have to resolve to something not even related to the current game’s events.
