They Annoy Each Other, But They Amuse Me

Maggie to Max: Hi, Mac!
Max: Hello, Maggie.
Maggie: More play, Mac? I wanna play!
Max: I am not called Mac. I'm Ma-X. M-A-X spells MAX.
Maggie: Hi, Mac!
Max: Stop it, Maggie.
Maggie: I love you, too, Mac.
Max: (Heavy sigh) Mama! Maggie is teasing me!
Mama: No, no. She's trying to say your name, but she doesn't know how to pronounce the 'x', so she's saying 'Mac' instead of 'Max'. You just have to keep reminding her, and showing her how to pronounce it the right way, and she'll get it eventually.
Max: Maggie makes a lot of problems.
Maggie: I'm me!
Max: I know, Maggie.
Maggie: I love you, too.
Max: I love you, too, Maggie. But you really need to learn how to announce my name.
