Dear John,
How are you? Everything is fine with me I haven't written for a while but I've been realy busy! Are you preparing for Christmas? Have you already bought gifts for your family? What about me I recently went shopping. It takes me a lot of time. I bought a T-shirt for my brother and a vase for my mother because her last vase was broken by cat. I have no idea what can I to present to my father. A seller advised to buy a cap, but I not sure about it. Also I bought smth to you. If you haven't bought presents and don't know what to buy we'll go shopping together.
Take care of yourself.
Best wishes,
Nick.
