Watched my neighbor try to teach his dog to roll over for like 3 months straight, same thing every single day, and that dog just was not having it. Then one random Tuesday the dog just did it out of nowhere like it had known the whole time. The guy freaked out, called his wife, made her watch like 15 times in a row. Point is some stuff just clicks when it clicks and all that bouncing around mightve been part of how you finally got there.
