you can't take a name where
every aspect is desirable in modern times
(short and feminine)
(exotic letters)
(v)
(two v's)
(snappy nicknames - avi, vivi)
(pretty unique)
("legit" for people who are concerned about legitimacy)
(pleasant meaning)
and
imagine that it's going to be "unique" for any significant amount of time. Do you really think liking
Aviva makes you above susceptibility to trends? How many parents who named their daughters
Ava and
Mia a few years ago are now tearing their hair in frustration?
Same logic goes for lovers of
Layla,
Adelaide, and
Evangeline.
