My husband knows some people who are in their late 50's. Whenever we invite them over, it's hard for me to call them "auntie" or "uncle" as they are still my hubby's colleagues and he calls them by their names. I just add "ji" to their name and it works just fine.
I think we Indians go over the board with our "uncle" and "aunty".
....hey, and my neighbor's daughter....I had my kids call her AUNTY JI in a singsong high pitched voice 😆 poetic justice 😉
agreed, this is common in subcontinental culture but i do ask some kids to call me aunty 😆 😆 😆 it looks cute 😛
