“I really don’t get why people say that I’m pretty, aren’t singers meant to be pretty? In our church, there’s a lot of people who are prettier than me. Why do they only say I am cute and pretty? I really don’t like people who do that. When I tell them my name, they say my name is pretty as well. Am I really that pretty?”
