One thing that's still there when you get home. What do you do in front of it?
What is waiting for you at home? Write about it.
Everyone gets the same subject. What differs is the follow-up: one question for children, two for teens, three for adults. Only the children's wording is simplified.
Write down one thing that happened recently. It does not have to be a good story.
Explaining is what stalls you. Put down what you saw and what you heard instead.
Find the sentence you are least sure about. What you actually meant is usually hiding there.
Instead of 'I was sad', write what your body did.
Write the visible, not the felt, and the reader stands there with you.
Open with a question and the reader keeps going to find the answer.
