Proper pronounciation

Aaron likes to say things accurately (accurate according to his little mind), whether it's sentence structure or pronunciation. He doesn't always pronounce his words correctly, but when he's absolutely sure he's right, he'll even correct others!

Case in point ...
Daddy: Shall we go and watch An-man? (spoke too fast, really sounded like "an")

Aaron: You mean AnT (emphasised T) man?

To be proud or irritated??!!
