I poured Moona and Buru two glasses of cold milk and ovaltine a few days ago. The conversation went something like this:
Moona: Shukran Mama.
Buru: (after a short pause) Mama mine.
Moona: She's my mother too.
Buru: Mama. Mine.
Moona: (calmly) No. She's your mother and she's my mother.
Buru: Mama mine!
Moona: (patient sigh) No. No-she's both of our mothers.
Buru: Mama MINE!
Moona: No! She's my mother too!
Buru: MAMA MINE!
Moona: She's not your mother only!
Moona runs out of the kitchen wailing, and Buru smirks.
