Remember, theme is "TheMessage" in the story. Grab supporting details that could include "because, as, etc." That explain some specific action happening. Always look for the cause and effect in the stories. When you explain in detail, you write "and this supports the theme of the story because (your answer here). Remember to start your conclusions with "Therefore, So on and so forth, In conclusion, etc." Hope I helped! (:
