As I was getting ready to go out for my run this morning.
E5N1 (coming down the stairs struggling with his bathrobe): The tie-things are coming from the inside!
Me: That's because it's inside-out.
[There follows a long and curious discussion about why he thought it was not inside out because the pockets are supposed to be on the inside or something. Eventually I help him to get it round the right way and then I reach around to get the belt to do it up.]
E5N1: What are you doing?
Me: This whole thing started because you were trying to do it up - right?
Me: No. Do it up ... right?
E5N1 (relieved): Oh!
He starts to walk away, then turns back.
E5N1 (genuinely puzzled): Up where?
