( 34.~35.) Hi, I am Jamie. My special place is in a big apple tree by my grandparents' garden. My grandpa built it for my sister and me. To get there, I have to climb up a ladder. Grandpa built it with wood and it also has a roof, so we don't get wet when it rains. I like to sit inside when it rains. The sound makes me comfortable. Sometimes I have food with my sister and cousins there. One day, I wanted to spend the night there, but it was really dark. I was afraid, so I went back to the house. vobiulp? Hi, my name is Karen. My special place is in a park near my home. I go there with my friends. It is not in the center of the park, so few people go there. There is a bench under a tree, and we often sit and talk there. It makes us very happy. There is a beautiful fountain and we often play water in it. It is a great place when the weather is hot. The tall trees there can help us keep out of the sun.
