OK, I need a new word.
Here's the definition: when one's inbox is so full that by the time an email is answered the sender has not only forgotten they ever sent it, they have moved on in their life enough as to be no longer interested in the topic.
Maybe I need more than one word.
One for that situation. Another for the email response that no longer connects with reality. Another for the sort of emailer I am.
One more thing: if I am the only person with this problem, kindly keep that information to yourself.
