I hope you and your family are doing good. I am writing this letter to let you know the way we celebrate independence day in Ghana. All the streets and roads are decorated with confetti. Firecrackers are being lit everywhere. The kids are getting their faces painted with Ghana's flag. My mother is also cooking a special dinner for all of us.
