Dear [Classmates],

I hope this message finds you well. I am writing to extend a warm invitation to all of you for a special gathering that I am organizing. This gathering is to bid farewell to our beloved teacher, and I would be honored to have each of you join us in this memorable event.

The farewell party is scheduled for [Date] and will take place at a casual barbecue location near my house. It will be a great opportunity for us to come together, reminisce about our school days, and express our gratitude towards our teacher for their dedication and support.

Please RSVP at your earliest convenience to let me know if you will be able to attend. Your presence would indeed make the celebration more meaningful.

I look forward to seeing all of you there, sharing laughs and creating new memories together.

Best regards,

[Your Name]
