Well your picture of two people holding hands as the sun go's down is one.
Try and get to the beach at say 7:30 PM! find a nice spot, and just have a drink and few nibbles...Listen to the Ocean.
You don't have to talk, let the beach do that....it is one of my most favourite things to do on hot summer nights.
There is something quite amazing, as you watch at night the waves come in....and listen to them. Few people do it, they all are home watching t.v.!
Take a blanket, and just have some quite downtime together, that costs very little.ENJOY!!
