I was just thinking a little while ago that
Kay and
Kaye are actually quite nice. And I love Kath, I think it's so chic. I think they're ready to come back.
Kathy I'm not as keen on, it's an "auntie" name for me, so it's a little dull. Cathie is kinda cute though, that spelling feels more fresh to me.
I think a lot of Kathys are becoming grandmas nowadays, so I wouldn't be surprised if Catherine/Katherine joins the filler middle name club, as legions of
Kathy's kids have kids.
