The problem with the artificial example is... I had that exact conversation with someone when I was taking algebra - and I mean that literally. (Though the x we spoke of was lower case
x
.) Just for the record, I'm an aspie, and I'm pretty sure the person I had that conversation with was, too - and we weren't actually serious. But we were both serious about having had basically that conversation with other people with various things substituted for x. — Ed Grimm 6 secs ago
