I was meeting with a potential client who had a project he felt more comfortable discussing in-person. 

Client: Okay, so this is one of those deviously simple ideas, but I need help making it happen. 

Me: Let’s hear it. 

Client: I’m surprised no one’s thought of it. I need your word you’re not going to just walk away from this conversation and use it. 

Me: You have my word.

Client: Double-sided PDFs.
