Quoting SmashleynSmallyPants:" no i think they would probably be teased for having matchy matchy cutsie names. People would like "omg ... [snip!] ... Flora and Fauna" like it just sets them up to be infamous for the names rather than what kind of people they are. Not a fan."
as a parent of twin girls (heh they are only 1 month old!) i have to say i completely agree.
they are two separate individuals who happened to be born at the same time. people will already tend to think of them as "together", why add to it?
why make them a gimmick by giving them matchy names like that?
