To build something means to construct something with materials. It looks like a bunch of parts, that come together to make one structure. One time I built a bookshelf with my dad. I felt excited to see it all come together, but scared that something would go wrong. I enjoy building things because I like to see how it ends up. I like the thrill of being able to create things. It makes it different from the activities I do enjoy because one of my favorite activities is running, but when you build, mor work goes into it. You have to measure draw and cut.
