What fragrance has ever made you wish for a do-over?

I was racing to a last-minute exam when someone’s perfume, a warm mix of tonka and rose, drifted past and triggered a memory of the first time I bombed a test. It was absurd and specific and made me want to crawl into a kinder version of myself. I learned later the smell was Chanel No.5, of all things, and that made it weirder. I sat on the steps outside the lecture hall for five minutes just breathing and laughing at how dramatic my brain was being. I walked in calmer than I’d felt all week and actually did okay. Would you go back if you could change one small thing?
