The Pitters' Place

So, I've found this lady attractive for whatever reason ever since I first saw her in Battlestar Galactica. I've also spent years knowing she reminds me of someone but not being able to figure out who that person is. Well today, while watching the new season of Longmire I finally figured it out mainly because that person was watching with me. It suddenly dawned on me that it wasn't so much that the two people physically resemble each other (although there is some slight resemblance) but because their facial expressions and general bodily mannerisms are almost exactly the same. So now I'm stuck with the knowledge that I've been attracted to Katee Sackhoff for years AND she has a resemblance and almost identical expressions/mannerisms to ... my baby sister. Yeah, if I wasn't a Tennessean I'd probably feel a bit icky right now.

what is the problem here exactly

I think it means I want to watch my younger sister pilot a starship and drink a lot. I've done one of those two things often.
