[Opinions] Re: Matchy Twin Names and Types of Matchiness.
What makes you so sure that people who name their twins "matchy" names didn't choose the names because they liked them?
People always treat twins as something of a package deal, no matter what their names are. Unique names or not, they often still just refer to them as "the Jones twins" or if they happen to meet one without the other they're apt to ask "Which one are you?" It's just part of being a twin, I guess.
My stepfather and his twin sister are Larry and Linda. They start with the same letter, yes, but those were also extremely fashionable names when they were born.
I have never heard of twins named Richard and Ricardo, or Paul and Saul, and doubt it's very common as those types of names are so difficult to distinguish by ear. In the old days, before there were reliable ways of knowing twins were on the way, giving such "lazy" names was just the parents making the best of having an extra baby arrive on short or no notice.
I think, therefore I judge.
