Answer:
Dear classmates,
I hope you're all doing well. It's been a long time since we've seen each other. However, in a few weeks, we'll be able to meet again.
On the 25th of July, our school will be hosting the annual alumni meeting. This year, they decided to invite the 2008 class. It would be at 8 o'clock, and you can bring someone else with you.
I'm looking forward to seeing all of you after all these years, and remember the good times we had in our school.
See you soon.
John Fisher.
Explanation:
When we write a letter, first we have to address to whom we are writing, then we write the introduction. In this first paragraph, we greet our classmates and introduce the letter's topic. Then, in the body of the letter, we inform them about the meeting, including the date, the time and any necessary information. Lastly, we close our letter expressing how happy we are to see our classmates and say our goodbyes.
