The From Behind Cuddle Attack!

Next time that you and your girl/guy are out, go somewhere quiet and intresting, like a museum. When your guy/girl is engaged in viewing an exibit, get behind them and put your hands on their waist, resting your head on their shoulder. Don't let it last too long, but it'll get their attention. Maybe if you're comfortable or further along in your relationship, a light kiss on the neck is a good idea as well.
