### Keyword Analysis:
- Occasion: Birthday. This is a celebratory, positive, and forward-looking event.
- Recipient: "Colleague friend." This is a dual-layered relationship. "Colleague" implies a professional, shared-workspace context. "Friend" implies a deeper, personal, and more informal connection. The recipient is someone you navigate professional challenges with but also genuinely enjoy as a person.
- Tone: The tone must expertly blend the professional and the personal. It should be warm, supportive, and friendly, but generally avoid being overly sentimental, crude, or unprofessional in a way that could be awkward in a work environment. It can be funny, but the humor should be safe-for-work and likely based on shared office experiences.
