First off, congrats on your first review esteve! Kaci is a sweet girl!
So what was I nervous about? Ever been nervous on the first day of a new job, first day of school, first date, etc.? That's what it felt like at first. I wasn't nervous my first time because I had been drinking. Second time I was nervous as hell and ended up getting hammered while waititng - I had gotten a hotel just for the occasion. As time went by, I was less and less nervous but it didn't wear off until about a couple months ago.
Maybe it could also be confidence..............but that's another story
