As I noted, it is possible to work around the need to actually talk about the diode in adequate detail. Like eg being hailed by someone in the street who knows who you are and launches into a friendly conversation while you desperately try to work out who they are. Perhaps that doesn't happen to you :-). Aha - it's Mr Diode!
