Never

Never have him do something that requires a specific outcome.

Never say something that requires a response.

Never ask him a question that requires an answer.

Never think you understand what he is saying.

Never ask him to clarify what he just said.

Never ask him to clarify what he just did.

Never trust him to follow through.

Never expect him to know how to do something that he did yesterday.

Never help him because you will only confuse him more.

Never assist him in gathering his thoughts because even then they will be disorganized.

Never have him get dressed twice in one day as he will not know how to do that.

Never guess about what he is trying to say as you will never find out for sure.

Never rush him as he will screech to a halt.

Never get frustrated with him as his behavior will become more confused.

Never depend on him as you will probably do it yourself anyway.

Never count on him in emergencies as you will probably have to take care of it yourself.

Never count on him in extreme emergencies as you will probably die anyway.

Never change the order or place of things as he will become confused.

Never expect him to find things even if they are in the same place they always are.

Never suppose he can see what you are pointing at.

Never think that when you touch something to show him what you are talking about that he will see it.

Never think that you can change subjects too quickly as most often he cannot release his focus.

Never ask him to bring you something as you will never get what you asked for.

Never be prepared as you will never know what to be prepared for.

Never

Never

Sometimes later
Sometimes tomorrow
Sometimes never again

Maybe not this time
Maybe not the next time
Maybe never again

Or not.
