How would you feel if I started correcting grammar and spelling in every post? At first you might thank me for my help, but I promise it would get old after a while. And what if I were correcting you incorrectly and you found out AFTER you built a bad habit from this free advice? It's social dancing, not a competition. It's supposed to be fun. With the exception of a very few partners I know well and even then only in certain situations, I hate getting corrected on the dance floor; it takes away all the joy of the dance. I especially hate it when I'm corrected for something I'm not doing wrong. There are people I won't dance with anymore because of this. And I am a teacher, and I hate it when I'm asked for feedback on the floor, except when it's my student or a friend and then I'm very gentle about it. I'm there to dance, not work. Schedule a lesson if you want feedback and I'll give it to you in spades.
