I just tried your example in GPT-4 and got the correct response:
>The man should tell the blind man to "pull" the door to open it. The reason is that the man sees the word "PULL" in mirror writing, which means it is written backwards. This is a common technique used on glass doors to indicate the correct action to people on the opposite side of the door. Since the blind man cannot see the instruction, the sighted man should verbally communicate the appropriate action, which is to pull the door.
