Proposal Idea #9: I-Spy. Set up a bunch of random items on a table and tell your girlfriend you and her will play a game of I-spy, just for fun. Make sure there is no ring on the table. Take turns and name some items, like “I spy a pencil” or “I spy two coins.” Play along a couple of times, finding the stuff each other says. After a while, say “I spy a ring”. She’ll look around and say there is no ring on the table. Then, take out your engagement ring and propose.
