Because....

Mommy: Why you don't want Ah Ma to shower you?
Dylan: I only want Mommy to shower me!
Mommy: I'm going to go back to work soon. You need to let Ah Ma shower you!
Dylan: I don't want you to go to work!
Mommy: How can I not go to work?!
Dylan: I want you to stay home with me!
Mommy: Why do you want me to stay home with you?
Dylan: Because I love you!
That's sure one good reason (:
