Thank you all.

I went for an 8 mile hiking after posted my reading. To my extreme surprise, I came back seeing you gurus' work. All your reading is great and wonderful, I am honored and inspired, and I learned from you. Thank you all!

Now that you like this kind of practice, I also posted the practice for 'S' sound above, with Cook's original recording. Hope you like it as well.

Have a nice week ahead.
