-The first word in each post should have a number of letters, which i s the average between the number of letters in the words in the previous post.
-The second word should contain an odd number of letters, when the first words contains an odd number of letters; and an even number of letters, when the first word in the post contains an even number of letters.
-Example: If the last post contains a 5-letter word and an 11-letter word, the next post should contain an 8-letter word (because 8 is the average of 5 and 11), and one more word with an even number of letters.
