Funny Story

So today as we are running around town Alexis starts copying everything Natalie was saying so Natalie called her a copycat. Alexis then said "I not copycat." So Natalie then said "OK then you're an echo." Alexis responds with "I not echo!" We then all start teasing her calling her either a copycat or an echo. And each time she responds with "I not copycat/echo!" Peter eventually says, "Ok you're an Alexis," to which she responds "I not Alexis." So I ask her if she's not an Alexis, then what is she? She answers, "Monster! Hahahaha!" She has such the sense of humor!
