Creat dialogue with 4 words per post. Each post should contain a 4 word sentence. Just one sentence and it should make sense on its own. Therefore,
NO LINKS ALLOWED! 
Sentences are preferred but in some instances, for lists of items etc., verbs may not be needed. Use good judgement. (Too, verbs may be implied.)
Example: First sentence: Give it a try!
Second sentence: You might like it!
Third sentence: Is it too easy?
