Tree house

Today I was building a tree house. I have a pen pal, her name is Kenzie. Back to the tree house, it's actually a cat tree house. I like building stuff for my cats. My favorite subjects are science and art. My younger sister ,Rebecca, is 8, my older sister ,Sarah, is 10 2/3. Next year we are going to Hawaii! Hawaii sounds like an awesome place. I cant wait to go! Kenzie is 9 I think she hasn't wrote back yet.
