Mine has pretty 'MEH' memory...He uses a notepad to take notes which doesn't bother me too much as I don't find it distracting.
He doesn't always remember as much as I would like him to though which at times can be quite annoying and hurtful. It's often only small insignificant things that he forgets which my rational self-knows is normal. He did one time forget the name of my deceased sister though and when I corrected him didn't seem at all phased that he had forgotten. I will often retell a story and he acts like it's the first time I've told him. I'm not sure is it for my benefit or if he actually has completely forgotten he already heard it. really help.
