What is the most embarrassing thing you've forgotten as a founder?

Not looking for the polished founder story here.

I'm talking about the email you forgot to answer for two weeks, the investor follow-up that disappeared, the meeting you completely forgot about, or the commitment you confidently made and then somehow erased from your brain.

We've been collecting examples of these “small” failures while building Luna.

They seem trivial individually, but I'm starting to think they're a pretty good map of where founders lose attention.
