    Hello! I' m John. I usually have a busy but happy weekend. I usually do my home- work first. Then I visit my grandparents on Saturday afternoon. They are very happy to see me. On Sundays I often play football with my friends. Sometimes I go swimming or go shopping. But I can't go out this weekend, because the weather report says it's going to rain. I can't play football in the rain. I can only play the piano at home. This is my weekend. What about you?

I'm two years _______than you.
