sentence words

Mummy teach me to speak in sentence words.

@Ikea - said "I want to eat grapes please, mummy" but I spoke each word in a loud voice ....to protest why must said it in long sentence? Can't I just say "grapes" only? The second video shown it all as I refused to say more than once just like reading a book in repetitive words.
Daddy said I am plain lazy :((. Mum also wants me to say it in mandarin.
