Present Concept for a Birthday
You've been talking to this girl, and you already know that music is her thing. Compile a playlist of her preferred tunes and others she might enjoy. You can burn the music to a CD or include a download link in an electronic greeting card. Include songs like "Happy Birthday" by Stevie Wonder, "Birthday" by The Beatles, and "16 Candles" by The Crests (16 candles, of course, if she's turning 16) on a playlist dedicated to her birthday.
Exhibit Your Imaginative Side
When shopping for presents, don't be scared to use your imagination. Don't gift her the same old stuff; show her you know her interests by giving her something truly special. You can create a photo book of your time together if she has an interest in photography. Invest in some canvas and colors if you learn she enjoys painting. The options are limitless.
Organize a Party
To show her how much you care, prepare a low-key party for her birthday. You can plan a pleasant outing to her favorite restaurant, a picnic in the park, or a movie night. It will mean a lot to her that you remembered her on her birthday by spending time with her. You can also learn more about her personality this way.
For the Avid Reader

For the Lover of Popular Culture
A gift card to a local movie theater, along with coupons for free popcorn and soda, would be a great present for a friend who never misses an episode of their favorite show. Perhaps she'll invite you along, too! Give them a DVD of a classic black-and-white film, or frame a poster from one of their favorite films. Alternatively, you might get them the final season of their favorite TV show on DVD. And if there's a one-of-a-kind play in town, offer to buy tickets and go see it with them.
Your Present
Consider presenting her with an everlasting bouquet of red roses, or her chosen flowers, to show her how much she means to you. Even a box of decadent chocolate truffles might be a thoughtful token of your love. Give her a huge birthday card to show her how much you care. Putting your concerns to paper may be less intimidating than coming clean in person. Take a risk and ask her out for a birthday meal just the two of you to fulfill her wildest dreams.
