Error

OK, readers, after reviewing my last post I realized that there was a error.

I work real hard to check my posts before I publish them. Sometimes...who am I kidding? I always quadruple check.

Here is the problem sentence:

He began by teaching me, from a prone position, how to sit up.

No, my physical therapist did not instruct while laying down.  I was the one laying on therapy table. The sentence should have read:

He began by teaching me how to rise, from lying flat, to a sitting position.

So now you know. I am a Grammar Nazi and I won't apologize ! Just deal with it.
