There are multiple reasons.

For one, I have made my intentions perfectly clear. It is no secret I am attempting to learn other ways of communication.

Two: Questions are asked and answered directly. I am making no attempts to phrase anything in such a way as to produce an answer beyond what each individual comes up with of their own accord.

And three: besides the changes in my own speech patterns, I am in control of no other variables. No manipulation. A perfectly innocent experiment.
