The sweetest sound in the world.
Love, miss, honey, adore, admire, desire. Is the sweetest sound in the world one of these? Of course.. Not. People love to hear this word on outings, dates and gatherings, and it's universally applicable to everyone. When you've used it enough, and appropriately of course, they take a subconscious liking towards you. So, what exactly is this magical word?
Yes, that's right, it's the person's name that you're out with which is the sweetest sound to them. They've heard it all through childhood till now, and nope, they're not even getting close to dreading it.
So, do mention your date's name as often as you can without it overdoing it and making it seem awkward. Don't end at "Good morning", use "Good morning, (name)." Nor should you end at "Good night", use "Good night, (name)." This can be used in many various situations, but just remember to check yourself every now and then to ensure you're not overdoing it.
So, if the only times you've been calling out your partner / prospect's name is when you're jogging silently to the rhythm of his/her name (i might be a bit guilty of this here), then perhaps you should start making it a habit to use it more, of course of the appropriate amount.
