1. Add one word to the end, beginning, or middle. But the sentence cannot exceed 10 words, so if the sentence is already 10 words long, you can't do this.
2. Take away one word anywhere in the sentence. But the sentence must have at least 2 words, so if the sentence is only 2 words, you can't do this.
3. Change one of the words to another word.
RULES:
1. Keep it appropriate.
2. The sentence must ALWAYS be grammatically correct.
3. If someone changes the sentence, don't change it back.
