Keke always asks us to fill out milk for her.
Last week, I told her that you are old enough to fill out milk youself.
Keke replied, "I will spill".
I said, "I will teach you."
Then I watched Keke open the fridge, and she did not where the milk was, and I had to tell her it is on the door.
Thereafter, she managed to fill out her a glass of milk, no spill. She then was rather pleased.
