I did notice that you are a very good listener

Or my brain had checked out. :D

I don't think you looked grumpy at all

Excellent. I've worked on that.

Speaking to a bigger crowd is my nightmare

Mine too. Was. For a long time. But then I forced myself to do that over and over again because I knew that I would also love it after I've gotten used to it. But sometimes when I'm in front of a crowd, I suddenly notice for some reason the the extrovert part of me bails out and the introvert in me is left all alone and when it's time to talk, I stutter, some words come out of my mouth in random order and I have no idea what I'm talking about. I hear the words that I've said with few seconds delay and I start to think that people must think that I'm on drugs and start to laugh because of that. Hilarious, sad and very confusing at the same time.

I can relate to you on the dancing part

When there's no energy for talking it's time for tequila and dancing.
