Thank you for the a2a! I have a habit of making mental errors; some funny, some not. This one just happens to be funny.
We had “open critiques” in art school. The idea was A- to point out how we could do it better, and B- to toughen us up for the advertising world. It’s brutal, cruel, and cutthroat, and get ready for your stupid clients to ruin your tasteful design and fuck it all kinds of up to put a picture of their ugly-ass crotch dropping on there, or a huge starburst that says “SALE SALE SALE!”. You had to learn not to care, and do your fulfilling artwork on the side. It’s just a job; nothing personal.
We were in the middle of a critique, and it was turning ugly. The only time our professor would jump in was if it turned personal. It had. He laid back and let us fight it out, until someone told the girl we were critiquing that “with your taste from growing up in a trailer park, looks like you’ll be working for the Auto Trader” (a shitty, newsprint magazine that people sell used cars in- the worst of the worst design jobs).
Before our professor could comment, I blurted out “For fuck’s sake, Mom….” I was about to say “tell them to break it the fuck up!” until the laughter started. Then I realized I’d called my professor, who had an MFA and spent 20 years in advertising at Saatchi and Saatchi, “Mom”.
He responded with such amazing, quick wit; “Ms. Hood, I admire your devotion to your mother; just remember she stays home while you come to class.”
I caught hell for it that entire semester. Luckily, we (almost) all had pretty tough skins, so it was amusing, even to our somewhat staid professor. He wrote on my end of semester assessment “Respectfully, Not Your Mom.”
I still keep that assessment to remind me to wear life like a loose garment. We all say stupid shit sometimes; just laugh at yourself and enjoy the silly moment.
