Yes... I swear I've spotted a few of them over the years. I don't think it's a hard thing to pick up on at all. If they switch, they're busted I reckon.
But given that some stats say up to 1% of the population have DID, then I also reckon I have missed many, many, many more than I have ever suspected.
I don't have a question so the same one for the next person.
