### Keyword Analysis
- Occasion: Birthday. This is a celebratory, positive, and personal event.
- Recipient: Friend. This is a broad but intimate category. The relationship can range from a lifelong best friend to a newer pal, a "partner-in-crime," or a long-distance confidant. The key is the warmth and informality of the relationship.
- Tone: The keyword is neutral, implying a need for variety. The tone should span from funny and lighthearted to heartfelt and sentimental to cater to different types of friendships and personalities.
- Core Component - "Pics": The inclusion of "pics" is the most crucial element. This signals that the user isn't just sending a text message; they are likely posting on social media (Instagram, Facebook) or sending a digital card with a photo. The wishes must work as captions that complement a visual memory.
