Just curious. Because I think it’s very “rude” in the Chinese Culture where I grew up in, to use the real names of people older than you. You have to address them by relationship like “father/dad” or “older brother” or “oldest aunt” “2nd aunt” “3rd aunt” (ordered by who was born first). Like I don’t think you are supposed to say Aunt [Name] or Uncle [Name]. Names are never used, only the relationship.
I’m under the impression that some Westerners, particularly Americans, apparantly are on first-name basis with parents… like either because they are very close, or very distant… is that really a thing irl, or is that just the media? I think I saw TV/Movie scenes where the kids (or maybe adult children) called their parent by their first names.
I don’t call my parents by their first names. Neither do my siblings.
My kids also use “mom” and “dad”, and we also use “mom” or “dad” when referring to each other parent to the kids.
My wife would call her dad by his first name, but only when she was calling him out for being goofy. In response to a dad joke, for example.
Personally, I don’t consider it a nickname. More like a title that I’ve earned. It’s like calling someone “doctor”. If my kids used my first name, I’d probably give them a raised eyebrow in response.
