When selecting a birthday gift for someone you're dating, it's important to strike a balance between personal and thoughtful. Think about what you've learned about their interests and preferences during your time together. If they enjoy a particular type of cuisine, planning a surprise dinner at a restaurant specializing in that cuisine can be a wonderful idea. Alternatively, consider an experience-based gift, such as tickets to a concert, a museum visit, or an outdoor adventure, which can create memorable moments together.
