They feel like they have a different vibe to me. I used to hate
Alice, mostly because people would call me
Alice instead of
Elise and that would drive me mad. I've changed my tune and now I have a perception of an
Alice to be intelligent, quick-witted, good sense of humor, sunny disposition, and someone who kind of just goes along to the beat of their own drum. This has no doubt been shaped a lot by the 4 Alices that I have known who range in age from 7 to 85ish.
I don't know what the vibe of
Elise is. I can't objectively assess that. But it feels different to me.
I dislike
Elisa. I pronounce it the way you prefer but I think the -a on the end seems unnecessary.
