Take a balloon (not inflated) and fill it with some confetti, then any thing that your life mate would enjoy. A love note. Some jewellery. Could even be an engagement ring. My husband used a balloon with lots of little ones inside to propose to me. Once you’ve stuffed the balloon take the balloon to a balloon shop and have them fill it with helium while the items are still in the balloon. You can of course use air if you don’t want floating balloon.
Attach a pin and a note that says; “Please pop” to the balloon string. Leave the balloon by your lifemate’s bedside before he/she wakes up in the morning. Or have it waiting when they get home from work
