Personally I prefer to be in trouble for doing something wrong than be in trouble for lying. Playing dumb works. I have couple of people at work who play dumb and get away with it. Until someone smarter comes along and catches them in a lie. I mean if it’s life or death situation I’d play dumb to save my life. In a normal, not the world ending situation I’d say “ I felt it was wrong but also thought I must follow directions plus my mind was elsewhere and I just let it go but now it bothers me. Would you like me to correct it? I’ll do it in no time”.
