It’s a funny thing, memory. Time passes, and we often look back with fondness to a moment that will trigger a passing smile. It can be the smallest thing too, and different for all of us. For some reason, smells are powerful triggers for me. I had one hit me like a hammer some ten or twelve years ago, that reignited a passion, left dormant too long. Oil burning on a hot exhaust. Not an attractive smell, I know, but sometimes the most memorable are not the most pleasant!
