Deleting your opening post is pointless. When someone has quoted your post, it remains on the thread (I quoted your opening post so it remains here from early on.)
Unless you really want people to look at your thread, don’t “delete” it. People looking at your thread is guaranteed be the result when you “delete”. You are really calling attention to something you apparently hoped would disappear.
You asked a pertinent question and there is no reason for you to be ashamed of that.
Good luck and have fun riding and learning. Don’t let anyone keep you from enjoying your riding education. It’s work and it is serious from a safety standpoint. No matter how old you are you have to be a good student, but, you should not pay someone to teach you if you feel they are abusive .
