If the last thing they gave you was a cool book, you could give them a book or movie in return, but you probably shouldn’t give them a nice watch or piece of jewelry. If the last gift you received from them was incredibly thoughtful, like a photograph in a frame, or homemade cookies, you should go for a similarly thoughtful and personalized gift, and not something impersonal, like a gift card.

A birthday gift will most likely be opened in front of an audience. Birthday gifts are normally not as romantic or deeply personal as a Valentine’s Day or anniversary gift. If the gift is for an accomplishment, consider the accomplishment. Flowers are appropriate for many performing arts occasions, while nice pens or certificate holders may be more appropriate for an academic achievement.

Science even says that recipients value these gifts more, because they can look back at the memories with fondness for a long time to come. Don’t worry about making the experience lavish or expensive. It is the thought that counts. All that matters is that you both have a good time.

Your budget will need to cover the gift, any batteries or necessary accessories, and wrapping paper/gift bags. Alternatively, make the gift yourself! Bake some cookies or make a scrapbook. If your gift is thoughtful, they won’t mind if it wasn’t expensive.

Look in their locker for ideas—what posters or photos do they display? Those could be clues as to what else they may like. Are they in clubs? Do they always talk about certain topics? Use all of this information to decide what gift to give. Take note as to how excited they get when speaking about certain things to know what are the best gifts.

Are they always complaining about needing something for their locker? That is something they will appreciate, and it shows you listen. Have you noticed their wallet is falling apart, or they are always losing their pens? A new wallet or a cool set of pens with something to hold them in would solve those problems!

If you’re talking about bands, you could ask, “Why don’t you have any posters or t-shirts?” They may say they want them, or they may say they don’t like the band that much. If a topic comes up briefly in conversation, ask for their opinion: “My family likes to go bowling a lot. Do you like bowling, or do you prefer mini golf?”

If the gift needs other items to work, like batteries or cables, get those as well. This way, they can use their gift right away. Check online for specific items that you may not find in a store, such as sold-out figures. Ask your parents for permission first, however.

A wrapped gift will be the easiest to hide in your bag; just add the bow at the last minute so that it doesn’t get crushed. A gift bag is another great option, as long as you don’t mind carrying it around. You could also just leave it in your locker. Use colors or themes you know they like. For example, if you know they like superheroes, choose something with a picture of their favorite action hero on it.

You should still give them a card, even if it’s an experience gift, like a movie. Mention the experience in the card so that they’ll have something to remember. You can buy your card at a store, or you can make one yourself. Even if you aren’t very crafty, you can make one using a computer and fun pictures.
