I haven't seen him for a long time.I want to spend some time with him.I'm going to take him around the park.On Sunday morning，I'm going shoppoing with my mother.I'm buying some clothes and food for my grandfather. In the afternoon，I'm seeing my grandfather off. I hope that you can look after yourself and have a good time on the beach.Don't forget to call me after you come back from the beach
