Summarize this article in one sentence.
One of the best ways to surprise your girlfriend is to take her to an event or activity she's previously expressed interest in. Not only will this show that you have been listening to her, it will show that you care enough to put effort into planning a date she will love. Here are some examples:   If you know she loves music, take her to enjoy a jazz concert in a garden, and pack your own picnic, complete with champagne. You can listen to the music together and cuddle up as the sun goes down. If spaghetti is her favorite food, take her on a date to an Italian cooking class. You'll learn to make pasta while also having a great time getting messy in the kitchen. Does she like beer? Plan a tour at a local brewery that includes tasting the  products they turn out. Not only will you get to try some tasty beverages, you'll learn something, too. Is France her favorite country? Plan a “French night” at your apartment. Buy French wine, have fresh croissants and cheese, try your hand at French cuisine, and put on a French playlist with Spotify. Light candles, and pull up a picture of the Eiffel tower on your laptop for effect. Voilà! A perfect evening in Paris. Have you always wanted to try wakeboarding but never had the chance? Having a girlfriend is reason enough for trying new activities. If your girlfriend feels like she is your “partner in crime,” she will realize she is an important part of your life. Having the courage to try something new shows her your adventurous side, a trait that many women find highly attractive.  Pick a unique activity: think whale watching, bouldering, brewing your own beer, or learning how to shear a sheep! The possibilities are endless. Get out of your comfort zone: dress up for a night and schmooze with the elite at an art show or gallery opening. Don't be afraid to look silly. Even if you aren't an "all-star" at the date activity you've chosen, showing your girlfriend that you have the confidence to try something different can be impressive. It will help build and maintain a happy, healthy relationship if you spend time together bonding as a couple without alienating those around you. Some couples practically disappear from their friends' lives once they start dating. That's a mistake. Your girlfriend will appreciate a balance between spending time with you alone, spending time with mutual friends, and spending time with her friends without you. Don't be offended. It's healthy for both of you.   Make a dedicated “date night.” Setting aside one day a week as a day that you will spend together (even if it's just an evening) is an important part of any relationship. It is important to show your girlfriend that she is one of your top priorities. Make this night extra special by trying a date idea suggested above. Schedule time with friends. Getting groups of friends together can be challenging, but scheduling a get-together well in advance can help make it happen. Send a Facebook invite or a group text suggesting a meet-up at a favorite restaurant, a local park, or a new bar. Be sure to invite her friends as well as yours. Double (or triple!) date. Planning a night out with another couple can be a fun way to maintain a social life while also spending important time with your girlfriend. Host a party. This is a great way to get all your and your girlfriend's favorite people together in one place at one time. The party can be for a holiday, a big sporting event, a birthday, or “just because.” This is a chance to spend time party-planning and practicing teamwork with your girlfriend.

Summary:
Plan a date you know she will enjoy. Try a new activity together. Plan to spend time alone and in groups.
