I was with some fairly new Canadian friends recently and "Valarie" by Amy Winehouse came on. I immediately started humming/singing along and one of them asked “what's this song?” I said (probably with a confused expression) “ It's... Valerie... by Amy Winehouse...” and they both said they'd never heard of her.
Now, I KNOW. I KNOW there are massive cultural, generational and geographical differences in what people know. Obviously I do. But for some reason Amy Winehouse is just so completely embedded in my personal schema that for a second I genuinely couldn't compute someone not knowing who she was. She feels (to me) like one of those people who are simply there in people's consciousness; whether you actually like them or they were ever particularly relevant to your life seems almost beside the point.
It made me realise how funny these little cultural blind spots are. There must be many things that are ubiquitous to one person, that another person has somehow just never encountered.
Have you ever had this happen, where someone didn't know something/person that you genuinely presumed consciously or subconsciously was universal known? And do you have a “surely EVERYONE knows who/what they are” person (or thing etc) that you'd be surprised if someone had no knowledge of that thing?
