Why only level 4? Because I'm managing to exercise more control. Why six? Because a while after the first five, I just felt like one more was in order.
You know what why means. You are not answering the question. Perhaps you feel the answer would be revealing, or uninteresting. But Isabel and I are both curious about why you are hitting your head against the wall. Is this literal or metaphorical? What drives you to it? What does it sound like? Do you have to repair the wall afterward? Etc.
To answer some of your questions, I have reason to suspect that it's audible over a telephone connection, and there's no need to repair the wall if it's somebody else's wall. Or if the wall is sufficiently hard, like the exterior ones in my house, or the plywood ones in the garage. Not all walls are so sturdy, though.
Why do you hit your head against walls?
Going to the Allegany Rogaine?
I see I'm going to have to go the hypnotism route to get an answer. Unless "Going to the Allegany Rogaine" is some coded answer and not a change of subject. I concede defeat for now.
Yes, I am indeed going to the Allegany rogaine! I'm on a roll! I am driving. Are you going?
