Am I annoying or is it everyone else?

So I have been going to class with mom to help out with demonstrating tricks and helping other dogs relax. I use to just sit in my crate quietly, but I have to be honest... I get bored. I need to work and play, so I have started barking. Julie and mom come over when I am quiet and give treats, but I still like to bark. Mom says I am annoying, but I really don't see it. I am just trying to be helpful and let her know that I ready to work whenever she needs me.
