Well, kinda. I assume you're talking about my cutesy version of her name. I didn't want to use her real name online, but I wanted you to know who I was talking about, so I used her childhood nickname.
And yes, she tends to use that voice when she's around close friends and family. When she's less sure of herself, she defaults to her less cutesy voice. It's a weird Kenneren thing. I suppose I do it too, to some extent.
