Dear Nancy,
I'm glad to receive a letter from you. It's nice of you to ask about my birthday. I celebrated it at home with my family and friends, then we went to the cinema. We had a lot of fun! I got lots of presents such as books, CDs, and other. My parents gave me tickets to aquapark and I liked this present most. I've got thousands of photos and some of them I will share in my social network. You can see them there.
It's cool your sister is in New Yourk now! What part of the city is she in? Does she like such a big city? Has she got friends there?
Best wishes,
