The thing I learnt is only assholes expect you to remember 100% of thing 100% of the time.
If you get asked something you can always delay them by saying “I added that to our documentation, let me pull it up”
Now suddenly you go from someone others think as doesn’t know anything, to the person who actually updates documentation with evolving changes.
Or he keeps losing it along the way.
