What should a desktop pet remember about you?

Mewmori keeps facts about you rather than a chat log: your name, what you work on, what kept you busy last week. A week later it brings one of them up by itself.

Deciding what belongs in that list turned out to be the hardest part. Names and projects are obvious. Moods are tempting and, I think, a mistake. Anything about health I ruled out early.

If something lived on your desktop and remembered you, what would you want it to hold on to, and what would feel like too much?
