Last Friday evening, I had a talk about my grandma. She told me that she wanted--visiting Shanghai. She would like to see the greatly changes in her hometown. Heard this, I began to book the air ticket for her on the Internet and I checked weather in Shanghai as well. After that, I helped my grandma prepare all the thing she might need during her trip such as a camera or a smart phone. The next day, I head for the airport to see my grandma off. Although it was a busy weekend, but I felt proud because I could do everything for my grandma. .
