The Key Culprit

GM: You holding the key?
Me: Yup...
GM: This morning YL ask me why I didn't lock the door?
Me: (what the fish)... I already instructed the person who had unofficially duplicated the key to lock it before I leave. I even walked to his desk to remind him lor. He still said okay.

'Okay' 个屁啦... kns... This guy just can't be trusted to do simple thing like locking a door. FYI, this is not the first time (in fact, as I was told, many times liao). Later if I see him, will tell him off!
