It was Grandpa's 70th birthday. Early in the morning, I wake up excited. Before getting dressed quickly, I headed downstairs and found Mum and Dad were already there busily prepared lunch. I checked the gift special made for Grandpa, a video of his life story. Just before lunchtime, there came some guests, who turned out to be Grandpa's best friends from secondary school, all in seventies. They had a great fun talking to each other. There were a lot of laughter and quite a few tear in their eyes. Grandpa said excitedly it was the best birthday celebration he'd had but that he was grateful for that we had done for him.
