I don't know what to do. I've said if they still want to do it at 18 they can. My major worry is that what they want to change it to isn't a name it's a noun. I don't want to say the name but think 'table' ' truck' 'monitor'
I worry that they won't be taken seriously when they get a job/career.
They don't want it to stay as a nickname but as their proper name.
What would you do?
