How much do you love your mom?

Teacher to child:

Teacher: how much do you love your sister?
Child: lots and lots and lots.
Teacher: how much do you love your mum?
Child: (thinks for a while, then..)
I love her as much as my sister.
Teacher: (laughingly) Heh, good answer..

Teacher recalled story to the child's mother later.
Mother: Heh, she's being diplomatic.

LOL.
