1. katie clean invited messy missy to her house to work on their biology project, but katie clean had no idea what a visit from messy missy entailed. first of all, it was raining and messy missy neither bothered to take her boots off nor thoroughly wiped them on the doormat. then messy missy ate a bag of hot chips on katie clean's white bedspread without asking, and messy missy is a sloppy eater, so hot chip powder got all over the bedspread. katie clean tried to be polite and ignore messy missy's sloppy behavior, but then messy missy threw her chip wrapper on the floor. offended, katie clean pretended that she was sick and asked messy missy to leave. the next day katie clean asked the teacher if she could work by herself. after explaining her situation, the teacher allowed katie to work alone. messy missy would have finished the assignment by herself, but she spilled grape soda all over her assignment.
what is the theme of the story?
