Client: Can you make me an ad for our upcoming banquet dinner?
Me: Sure! What are dimensions?
Client: I don’t know, that’s your job.
Me: If I asked you to paint a room in my house but didn’t tell you what room. You would ask me what room to paint, right?
Client: Right but what does painting a house have to do with graphic design?
Me: Well, in this scenario, you’re asking me to paint a room (design an ad) in your house and I’m asking you what room to paint (dimensions to make the ad in).
Client: Listen, can you do this or not?
That’ll teach me to use a metaphor.
