Following my recent encounter with a floor to ceiling glass window I’m perhaps not the best person to be commenting on other people’s vision. When we checked into the hotel earlier, Mike holding the room key first boldly led us from the lift down the wrong corridor, (even though the sign was clear) and then spent a minute or two trying to get into our room before the door was opened by the actual occupant, who pointed out we were looking for 407 (and not 408 the room we were attempting to enter). The way me and Michael are heading we’ll be needing a white stick and a guide dog soon!
