Instead of focusing on a nickname, try to get to know the person better and learn about their individual preferences. Here are some respectful ways to approach this:
* Ask directly: The best way to know what someone prefers is to ask! "Do you have any nicknames you like?"
* Listen for cues: Pay attention to how they introduce themselves or how their friends address them.
* Use their full name: A simple and respectful option is to use their full name until they tell you otherwise.
Ultimately, showing genuine interest and respect for the individual's identity is the most important thing.
