When I read, "Let it go" I think of the episode of The Big Bang Theory when Penny tries to teach Sheldon to let things go. She tells him to imagine that he has a pen, then he has to let it go. He's upset because he imagined an ornate pen that had his initials on it. Therefore, even though imaginary, it was precious. Things got weird(er).
And when I think of "Let It Go" I hear the song from "Frozen." I have heard of the Big Bang Theory, though. My son and his wife watch it all the time. I've managed to walk in and watch about five minutes of probably a dozen shows each.
Frozen, though, I've seen in its entirety probably three times now. Just watched it again over the weekend. I wonder what that says about me. :)
Probably that you have young people in your close proximity... that or you have a magical, whimsical side. :D
Funny thing is, even though the first part of that is true, there are so called "kids movies" I'll watch that some of them won't. Go figure. Animated movies are some of the best entertainment there is, especially the ones who try to reach a broader than younger audience.
I've never seen The Big Bang Theory, but that sounds funny! :D
