I don't know about other patrs of the world but in the UK, youngsters were expected to refer to older ones as AUNTIE or UNCLE. I didn't like this at all!! I publicly told my children NOT to do this, i thought it was reeeeally creepy. My main reason for this is that i think it creates trust in people that are strangers to the family unit and for some kids, it's part of the grooming process for molestation. Kids trust people that they see as auntie or uncle. I think it's very sinister and much more appropriate to refer to older ones as simply Brother or Sister. in the non specific Brotherhood sense. I just wonder who started this trend.
