The Prom-Puzzle

This puzzle was crafted April 13 and unveiled April 14. It involves the target (Annie) receiving a series of envelopes throughout the day. Each envelope contains jigsaw puzzle pieces, and when put together, the pieces say "Come to Room 368 after school for a SURPRISE" Once Annie enters 368, I prompose to her. It took about an hour and a half to prepare, but it was really fun.
