I hate when people are rude during free lessons. I gave my ex's little sister lessons for a while and I'll I would hear afterwards was, my mom says this, your wrong about this blah blah blah.
She was like 6 years old and never been on a horse before trying to tell me I was wrong. I mean I paid 20 bucks an hour to learn to ride. And that was for group lessons. My horse bit her when she was trying to feed her because I was 'wrong' about keeping your hand flat. Hershey got lots of secret love from me while she was crying. Lol.
