The Day X Ran Away

There are but twenty six letters in our alphabet, yet together, they can form hundreds of thousands of words. Some letters—L, N, R, S, T, M for example—appear in more words than letters like Q, X, and Z. X checks his personal dictionary and is distressed to find only sixty three words beginning with him (X.) Feeling unimportant, he decides to prove his worthlessness by running away, leaving the other twenty five letters to make words without him. To his great surprise, X discovers he is needed to complete words started by his twenty five friends.
