If only people came with ideas, you can work with that. It's the vague terms with no explanation that I have trouble dealing with.
"I want it to be more fun", "It's just not quite right yet", "I want it to pop more", "It's not grabbing me yet" etc. etc.
And when you try to get more clarification you get blank stares.
Imagine if someone came to you asking you to analyze some proteins but when you ask what sort/which ones they just shrug and say something along the lines of "I dunno, the right ones".
