Answer
Brief Explanations:
The first sentence uses full - form words ("I am") and a more neutral and polite tone. The second sentence uses contractions ("I'm") and an informal phrase "fed up", making it less formal.
Answer:
I am writing to express my dissatisfaction with the library's reduced hours.
