Yep she went right out and hitchhiked with a stranger./sarc. I hope you really understand that it is something called a promo, which involves actors and props. And how do you know that she doesn’t teach Trig better. Obviously, this was something unusual for him to do, or no one would have grabbed a camera.
Obviously Sarah was not out thumbing it and obviously they thought it was cute for the fairly large boy to stand on the dog.
Promoting the wrong message, thumbing it and the dog thing. I just don’t think she cares to promote another turn in the “POTUS campaign” barrel. Happy she has found financial success instead.
