When I related my conversation with my dad in my previous post to my friend. She said this has got to do with our parents failing in memory.
She experienced the same thing herself when her dad bought her prawn noodles for lunch. She stared at it for a moment and told her dad that she'll eat the noodles and he could have all the prawns.
Her dad thought for a moment and both of them started laughing! That's because my friend is allergic to prawns since young!
My friend said that men never knew how to express love to their children and this is probably the best they did. I pondered over this for a long long while.
