Susan. I love the way it makes my mouth feel to say it, like I’ve eaten something sweet. It’s soft but grounded. Plus it has some cute nicknames like
Susie and
Sukie.
Lois sounds like “lowest”, it doesn’t have any good nicknames that I can think of, and when I say it, it’s one of those ugly back-of-the-throat names, like I’m going to gag. I do like
Louise, which is similar, because the soft, smiley ending redeems that one.
