Raine and Storm - Cruel, cruel, cruel! I would really hate my parents if they did this.
Bonnie and Clyde - Cruel, but by the time their friends know who Bonnie and Clyde are, the teasing years will basically be over. However, it's still cruel. Plus, they aren't great names.
Luke and Leah - Cute. I usually dislike names that start with the same letter, but at least these aren't overly matchy. They flow nicely together.
Billie and Jean - Not overly cruel, but not cute either.
Reagan and Kennedy - Cruel.
Mona and Lisa - Cruel!
Leon and Noel - I have to admit..I kind of like it. I wouldn't do it though, but it's cute. And unless their names were written down, you wouldn't even notice to connection.
Isaac and Isaiah - Cruel!
Jayden and Jaylen - Ugh..cruel for so many reasons.
Barbara and Kenneth - Haha. It took me a minute to realize this. It's very cruel actually.
Harry and Hermione - Cruel!
