I have brought this here as it is massively off topic
You have taken the part you have quoted out of context, your complaint is about similar spelt names, they do sound quite differently if spoken
You have stated that you cannot tell them apart from their physical features
I’m not dismissing the importance of names
my point I was trying to make in this instance was it didn’t matter if one was called JJ or Peter Robert if you are not able to tell them apart,
I was trying to say it didn’t matter if they had extremely different names or similar names, you would still have the same issues telling them apart because the issue for you is Physical features and not what names they are called
