My mom explained to her (not thinking that Ayana would understand at all) that, no Mama didn't make the leaves change colour, but God (Baby Jesus' Ababa) sure did. Ayana nodded, and pretended to understand completely, and be all together very wise about the whole thing.
The very next day, Ayana looked out the window again, and looked at our tree, nodded, and said, "God did that". She then looked down our street, gasped upon seeing that there were many of the same things happening everywhere, turned to my mom, and said, "God did it AGAIN??"
Since then, whenever she sees the trees changing colours, she looks at whoever happens to be nearby, and tells us that, "God did that. God did the trees."
And, of course, as Moses has to be the same as his awesome big sister, whenever he sees the trees, he shrieks "God trees, God trees!" while clapping his hands.
