It's definitely not right in cases of adoption. I had a little girl in a class that I taught, and she and her brother- both with incredibly distinctive first names- were adopted, admittedly in another council, but not a million miles away from where they were born. I always wonder if they managed to stay under the radar, away from their birth family, for their own safety, as it wasn't recommended that their first names were changed after the adoption. They will now be in late primary/early secondary school, and I do hope that the adoption went well for both of them. The little girl was lovely!
The only thing that I do object to is disclosing why I would like an appointment, because I grew up in a village where everybody knew your business and your family, so attempting to maintain any form of privacy required a lot of effort!
