It’s a similar thing with four leaf clovers - I never in my life found one, even during periods where I’ve been scanning every bit of green while hiking. But then we had a friend who isn’t really paying attention to her surroundings, and just randomly goes ‘oh, moment’, and picks up a four leave clover from a few metres away.
Seems my daughter is also developing that talent - last summer she picked up a few while playing outside.
