Yesterday when I was riding Jubilee she decided to be a dork and evade contact, by either sticking her head way up high or way down low. Either way, she was evading my contact. She was also being speedy when she was doing this too. Sometimes she's perfectly fine and responds awesome. Maybe it was an off day. But I don't want her to get away with it. She definitely knows better and it should NOT be happening. How do I deal with this? How do I correct it??
