This isn't a TAAT but I wondered how other parents would feel about their child changing their name. It seems to be the accepted view that if your child identifies as non binary of trans or similar, they change their name and their parents are supposed to not have any issue with it.
But I think I would and I think a lot of other parents would too. Whether it was to do with an identity or any other reason. There is so much agonising that goes on here about choosing a baby's name or fury when other people mispronounce or misspell that name. And yet parents are apparently supposed to just say OK fine when they're teenager suddenly decides they no longer want their carefully chosen moniker.
