Constructive criticism, a forgotten art form

I've always been happy to collaborate with clients. You have ideas? Great, bring them to the table and lets solve it all together. No problem.

For the past week, I've been in Keynote/Powerpoint purgatory. Trapped with one of the VP's of sales. He has very strong opinions. I can respect that. He seems to like working with me better than anyone else in the creative department. Clearly a man of taste. However . . . he jumps on me for missing a text update buried in a chart. And then the next night, misses my email that says, "sending you the first three of four pages to make sure we're on the right track". When he writes back to give me feedback, he says, "Last page missing, info incorrect. Can't use this tomorrow."

Repeat cycle. And rinse the irritation each time if you can.
