"No," I tell them, "No, you're not. You just haven't learnt. I can't drive. I'm not stupid, I just haven't learnt. I can't play the piano. I'm not stupid. I just haven't learnt. I can't make a lemon meringue pie. I'm not stupid, I just haven't learnt."
"But I don't understand all the terminology."
"It's just jargon. I can't follow a knitting pattern. I can't operate an SLR camera. I can't follow cricket. I'm not stupid. I simply haven't learnt the jargon."
Then I point them to the stupidest remarks I can find on the internet - on a news site's comments page, on Twitter, wherever.
"Look at that. That person created an account with username and password, logged in, and posted a comment of complete imbecility. To do that they needed a computer. OK, it might have been with a smartphone or a tablet, but they are computers by another name. And you're saying you're more stupid than them, because they know how to do that and you don't?"
The assumption is that because computers have become so commonplace, most people know how to operate them, so anybody who never got around to learning must be stupid. But the same could be said about cars, yet none of my self-declared "stupid" friends tells me I'm stupid because I don't know how to drive.
I find this self deprecation really irritating. Is it just me, or does anybody else not know how to make a lemon meringue pie?
