Was I smoking Angel Dust or did Natalie say something about the world coming to an end because the Chinese might bomb us to avenge Hiroshima? Granted, Natalie's history snafu seemed a bit more Sunset Tan than Top Design, but I am always up for a bit of reality TV idiocy and Natalie delivered. Paging Joel McHale. Thank you Natalie for your priceless quote! Luckily for Miss Natalie, this week's episode wasn't a history test, it was about collaboration. I thought it was a brilliant challenge because interior design is always collaborative -- decorators have colleagues, vendors, contractors, and, most importantly (and often most nightmarishly), CLIENTS. It's a psychological minefield. A designer needs to lie, cheat, steal, and steamroll over obstacles to realize his vision, all while pretending to listen to others and always with a big smile. The designers who played well with others all did magnificently.
