Date: __/__/____ (Date)
Dear _______ (Name),
Hi, hope this finds you in good health. I am doing fine here.
It’s been a long since we met. I know it’s been 5 years after college, and I have been waiting for this event for a long time. We have planned a reunion on ______ (Date). The venue is ______ (Name of the venue). We are expecting the presence of all the batch mates of our session. I really hope you will take a little time out of your busy schedule and attend it.
Please file for leave applications as soon as possible. The reunion will be bringing a lot of memories back and might even give us a little time to live our college life again. I expect to see you on that day. If you have a partner or spouse, the person is heartily welcomed. Please do write back with a response. I will be waiting.
