Re: some twins I know (or have heard of)
Georgia and Holly - Georgia, yes, Holly, no.
Areta and Alexandra - Areta, eeek!, Alexandra, pretty.
Sophie and Claire - love them both.
Kylie, Elise, and Jaimee - Kylie and Elise are fine, don't love them but don't hate them either. I think Jaimee should only be used as a nn for James.
Kelly and Aaron - Like Aaron, but Kelly will always be a girls name to me.
Megan and Jessica - Megan, yuck! Terrible association with that name. Jessica is pretty.
Terena and Kristy - Terena.. um... NO! Kristy is on the same boat as Kylie and Elise.
David and Peter - love!
Benjamin and Jacqueline - love!
Elise and Nathan - Don't really like Nathan.
