A typical male advice, Bobert. It would not help at all (except making him feel superior). Women do have superior memories for these details but not quite as good as some think they have.

Bobert's idea: Write it down and confront her with the facts when she complains with (in her mind) a good reason and has a bad mood.
What was without the confrontation with the facts? She had a bad mood and a reason for it. Go out with her to have fun and she'd probably have a better mood than before.
What will be after the confrontation with the facts? She'll still have the same bad mood but no reason for it. That's much worse.
