6) This weekend I am going to go to hang out with my close friends. We have decided to watch something funny, so I think that we will spend a nice day. After the cinema, we will go to the cafe to eat pancakes and drink soda. I think that we will have a lot of fun together and my weekend will be interesting and relaxing!
