Tara: Mummy, will you (grow) old?
Me: Of course, we all will. And Mummy will grow old just like Grandma. And you will grow up just like Mummy.
Tara: No! (Wailed slightly), I don't want you to (grow) old!
Me: Why not?
Tara: Because I don't like old. I don't want you to be old.
After a while...
Me: Tara, if Mummy don't grow old, you won't grow up too you know?
And Tara gave me a knowing look after that. I guess she can't wait to grow up?
