With such an artless phrase as “What else has this guy done wrong?” I’d wonder why you think you have any wisdom to impart?
Then again, you said you get work FROM professionals. You didn’t say YOU are the professional. So, since you obviously know your place, I guess I can’t fault you too much.
Now, if you are done worrying about petty minutia, did you have anything sentient to say about the actual topic... aw, never mind. I’d only wonder what else you’d “done wrong” if you’d bother.
And nice try at snarkiness, but somewhat inadequate. As my dear old dad says, if you can't tell me to pack my toothbrush and go with the sheriff, it doesn't really matter. My Martindale's an AV, if that means anything to you.
