Once upon a time, a young teenager named Alex decided to write a letter to his pen pal, Sam. Unsure of how to start, Alex asked his older sister, Mia, for help. 'The most important part of an informal letter is its casual, conversational tone.' Mia explained, 'Start with our address in the top right corner, followed by the date.' Alex nodded and began writing. He then asked, 'What comes next?' 'The salutation or greeting.' Mia replied, 'Since Sam's your friend, you can start with a friendly 'Hey Sam,'.' Next, Mia told him about the body of the letter. 'This is where you share news, ask about Sam's life, or discuss anything you want. Make sure to write in paragraphs for each new topic or idea.' Finally, Alex learned about the closing. 'You can end with a casual 'Cheers,' or 'Talk to you soon,' followed by your name. Remember, informal letters are just like a chat with a friend, but on paper.' As Alex finished the letter, he realized how simple, yet powerful, informal letter writing could be. Through a mere piece of paper, he could share his life, experiences, and emotions with a friend miles away.
