Simon, We had hiking in 2011 with your family. You held Hey Hey (熹熹) when he was tired or when the road was rough. Sometimes, you held his hand and walked together. Sometimes, you let him walk by himself. Although we finished the hiking very quick as the route was short (西貢大網仔路), we’re very happy. In future, I hope Hey Hey will enjoy similar healthy activities with us. R.I.P. Simon
