what is the difference between [Don’t] and [do not] (or) is there any differ at all?

Also, I really like the way you instruct your lessons. You make more since in the way you teach, than any teacher, I have tried so far.

I need a lt of correcting in my language (speech) because, I came from: ‘Down South’ and by the way…I did see your video on this topic…and I must say, it was very funny, but teachable in a unique style….which was a plus for me.

Keep it James, you are discreetly, a very good teacher.

“If I have used my language out of place while speaking to you….please forgive me….that is why I am here to learn….(smile)

Wednesday, September 4th 2013
