On Saturday I went to and exhibition about The Beatles with my friend. And we bought some thing from the souvenir shop.
What did you buy?
Some postcards and a CD. What did you do last weekend?
I didn't do anything special. I went to the cinema with my brother.
What did you see?
We saw Batman V. Oh, and we met Julia outside the cinema. Then we had a hamburger.
