We had *plans*. I love spending time with MrsZ, but since this wasn't a big anniversary we had a day of stuff to do.
But I am cooking a nice dinner, and we have a bottle of bubbly open, so there's that.
Only once have I gotten the yips so bad I couldn't play (wrote about it here a couple of years ago). Nervous is normal! You want your performance/recording to be the best it can possibly be. Use that nervous energy to fuel the performance/recording.
