ic... y and ie nns for MOST (not all) fuller names sound EXTREMELY childish to me and I'm not a fan of them in most cases... Thus, calling adults
Katie or
Susie instead of either
Kathleen (or other variation) or
Susanna (or other version) ore even just
Kate or
Sue feels strange to me (Same with
Billy or
Bobby on men, though Billi or
Bobbi on women don't bother me so much since the shorter versions would be confusing)... like I'm talking down to them or something even though I'm not... I usually prefer full names anyway. The exceptions to the ie nn thing for me tend to be certain nns where they're cross-gender nns that could be used on either gender... like
Dani,
Frankie,
Bobbi, Robbi,
Cori, Billi,
Stevie (this one partially because it's a refreshing change from
Stephanie), or
Toni... the ones where you can't very well shorten it to its simplest form and still sound at all feminine. I like
Ricki too, but it stands as a name on its own. The only spelling I can stand for
Deborah's short form is
Debi... and even that I have an aversion to. Otherwise, the nicknames like
Joey,
Kimmy,
Susie,
Lenny,
Chrissy,
Jenny,
Davy,
Becky,
Johnny, etc. just sound like someone's trying to hold onto their childhood still when they're 30 or 50 and it strikes me as odd. Thus, unless the name is a full name in its own right and not just people being lazy and not using a/the full name, I'd have an aversion to that.
