Not long ago, I suggested taking your sweetheart kite flying. Here’s a variation on go-fly-a-kite.
Buy/build a kite for your sweetheart to fly. When he/she’s not looking, attach several love notes to the tail of the kite.
Take the kite out and let your sweetheart find those notes. This means you hold the string-end and your sweetheart hold the kite.
If you have a romantic idea, share it. We can all benefit. Robert
