There is a guy in an organization that we’re involved with that doesn’t read replies to his emails; but, sends new emails about the same topic. Then he’ll be confused because we’re assuming he read our earlier email. We know he’s absent minded and try to keep our responses very basic; but, that doesn’t seem to help much. And he’s even worse remembering conversations. We try not to complain since he’s doing something that we wouldn’t want to do; but, interactions with him can become quite frustrating.
