For a graduating class
Graduation is the last day everyone is in one place. Ask each person to write what they think will happen next, seal it, and open it together at the reunion in five or ten years.
A teacher, class rep or friend creates the capsule and sets the reunion date.
Everyone writes from their phone. Nobody can read anyone else's letter.
Each classmate who's listed gets an email that morning. Read the letters together.
Pick two or three. A few honest lines beat a long letter nobody finishes.
