Sampling some fresh donuts or splitting a sandwich from a deli are great ideas, if you're into food. Surfing, boating, or hiking are good if you and your date are more "outdoors-y" and athletic. If you both like movies, you can schedule a marathon of favorites, and maybe prepare a menu of foods related to those movies. Nervous about talking to someone one-on-one? Make it a group date and go with a bunch of friends! Group dates are especially fun, because it gives you the chance to learn about the other person's friends, too! Looking through a book shop or record store is great because you can share personal tastes about books or songs with each other. Or get creative and write some poems about each other. If you're old enough to drink, try sampling whiskey or craft beers!
Even now that I'm married, my husband and I still try to schedule time for little "dates" together. We usually go for a walk on the beach, or do some shopping at the farmer's market, or just sit next to a bonfire roasting hot dogs. We always try to find something that both of us will enjoy and connect over, bringing us closer together.
