Well I would say do an event that is most signifigant to you. It could be a Tragic or Happy memory, or one that is simply close to your heart.
You can start by repeating the question like if it was "where does water come from?" then you ask: where does water come from so add a little introduction and answer and it becomes: Where does water come from? water comes from this and that and that and this but also this and that and it all does this and that while that and this is happening
Whenever.....
