If you are droning on about Photoshop then you are a poser that has no clue what Photoshop is used for. It's a canned Lemming Troll for idiots with no real clue.
I do my professional work with Photoshop. I wouldn't say I'm an artist (artists don't paint with computers), but I have very professional use for it. Yet you say I have no clue what it is used for. Care to tell me what it's good for, then?
If a subordinate asks you a pertinent question, look at him as if he had lost his senses. When he looks down, paraphrase the question back at him.
