Conversation with Tessa

Tessa: Mommy Mommy buy me a big big chocolate ice-cream!
Mommy: Are you a good girl?
Tessa: YES! I'm a good girl.
Mommy: OK are we going to buy one for didi too?
Tessa: NO!
Mommy: Why?
Tessa: Because.... Didi is so naughty! I am so angry!
Mommy: What did didi do to make you angry?
Tessa: Didi cries because he wants milk.
Mommy: Didn't you also cry when you want something?
Tessa: But... But... Didi cries so VERY loud.
Mommy: OK, but are you going to share your ice-cream with didi?
Tessa: (tapping her pointer finger on her chin and thought for a while) I think so....
