Dear ,
How are you? It has been a long time since we last contacted each other.
How are you doing in University? Is it stressful? Mine is great. I feel more relaxed and we have more freedom now.
Next month, we will be holding a New Year celebration, which will also be our class reunion. I really hope that you will be able to attend. It will be a great chance for us to catch up with one another and I believe we will have a great time.
I will be anticipating you reply! Hope to see you soon.
Yours sincerely,
