Final answer:
The letter is too informal and contains an unnecessary explanation before closing.
Step-by-step explanation:
The letter does the following things wrong:
- It is too informal.
- It contains an unnecessary explanation before closing.
The letter is written in an overly casual and informal tone, using phrases like 'Hey bud' and 'It's great to hear from you'. In a formal context, such as an email to a teacher or a professional email, it is important to use a more formal and professional tone.
Additionally, the letter includes an unnecessary explanation before closing, with the writer saying 'I have to get going, I still have a billion things to take care of'. This information is not relevant to the purpose of the email and could have been omitted.
The letter written by Freddy to Javier does not contain any professional errors. It is appropriately informal given the context of a personal letter between friends. There is no unnecessary apology or explanation before closing, making it suitable for the friendly tone of the message.
In contrast, a professional or academic email, like the ones illustrated in the other examples, would need to adhere to certain standards of formality, including a clear subject line, proper salutation, capitalization, politeness, and a sense of urgency or timeliness if needed.
