There are certain expectations that are put on you as a child actor, but mainly it's just turn up and say your lines with a lot of energy and a cute smile.
I'm only being cute here. I don't really mean it. I just wanted to make you smile.
I'm just saying, 'Hey, throw me a bone. How about a smile, cute t-shirt? Look at me.' Nothing - unless it's a turn to their friends to go, 'Hey, why is that weird guy looking at us?'
Cute is when your personality shines through your looks.
A smile is the light in your window that tells others that there is a caring, sharing person inside.
