• Check for comfort: Pay attention to her reaction. If she smiles or uses it back, it’s a good sign. If she seems uncomfortable, ask privately if she likes it.
• Consider context: Some nicknames are best kept private (e.g., funny or silly ones), while others work in public or on social media. Respect her preferences in different settings.
• Be consistent: Once you settle on a nickname, use it regularly to make it stick. But be ready to adapt if she outgrows it or wants a change.
