The audience and your connection with them will vary depending on the answer.
Maybe it’s been four hours since dinner time and everyone is a little on edge. They’re antsy and expectant, so there’s a huge spike of energy when you hit the stage and then the crowd is exhausted…but you walk away thinking they loved the first part of the show and hated the rest.
Maybe you put on a great show and they just needed a snack.
