Go for a walk or car ride and then for ice cream or cappucino.
Go to lecture or cultural event on a topic that you both find interesting.
Visit a museum or art gallery.
Go window shopping in an ethnically different area than you live in – Chinatown, Italian or Greek district.
Go to a store and amuse each other by both trying on silly hats – for this activity you must be agile enough to beat a hasty retreat.
Just enjoy each other’s company.
