Today is September 23rd. It’s the Autumn Equinox. Lily goes out with her mom and dad. They pick green “autumn vegetables” in the small field. Then Lily flies a red kite. It looks like a little fish. Dad helps her hold the string. Many kids nearby laugh and fly kites too! In the evening, mom cooks warm “autumn soup” with the vegetables. It tastes good. Lily smiles — she has a really great day!
