here is a conversation i had with my team leader when i got into work this morning:
TL: Oh, hi Sara. You snuck in today.
Me: Like a ninja.
TL: A what?
Me: A ninja.
TL: I don't know what that means. I've only heard the word.
Me: Ninja -- Silent, sneaky.... deadly.
TL: What is it, like an animal?
Me: No, a person!
TL: Is that a real word?
Me: Yeah! Ninja! Silent assassins. You never see them. You never hear them. Until it's too late.
TL: But, what--- Nevermind.
