It started with a letter

Letters form words, and words form phrases/clauses/sentences. Sentences form paragraphs, and paragraphs result to any kind of writing. First, it’s just a misused letter that could result to a misspelled word, later, your whole writing is already stained, then your grade would rely on what you did. Now, you’re bothered if you’ll fail or not. Imagine, it was just a letter.
