Here is the completed email: Hi Stan! I'm very happy **because** you are coming to stay at my house this weekend. Mum wants to do the shopping **because** she wants to know what food you like. Do you eat meat? For breakfast I usually have milk and cereal **because** it is quick and easy. I also drink apple juice **because** it is my favourite. What would you like? We can go to the beach on Saturday **so** let's take a picnic lunch. What would you like? I love chicken and chips. Can we have that for dinner? Do you like chicken and chips too? Bye for now! Steve
