I had at least 2 distinct crushes on her
I was 8 when Escape to Witch Mountain came out (which I loved for MANY reasons, Kim amongst them). I had a big crush on her... then, 4 years later, I had a separate crush on her character Ruthie, in Hello Larry and Diff'rent Strokes. But I never realized they were the same person! How pathetic is that?!?
Well, kids were more clueless then... and also, four years to a child is like... frankly, I would say that four years to a child feels like more than the entire length of time we spend in adulthood, subjectively speaking. Seriously. It's at least 80 or 90 GUYs (Grown Up Years).
Aaaaaaanywho, this is so cool, decades later, to be able to say "you're a babe!" on a computer. I hope you read this Kim! And get back into acting NOW! You still have an audience.
