It works like this. My brain has spare capacity. When I am concentrating on an easy task, my brain wanders off. The unused capacity has nothing better to do. If I introduce music, then my brain processes the music, which takes up some of the spare capacity. Thus, my mind wanders less as I do the easy task.
Hers Truly surprised me again yesterday. She got her white nightgown dirty, so she wandered into the bathroom, got out the heavy-duty soap, and proceeded to clean the stains out. She did a credible job.
I definitely have a can-do girl. If we don't show her how, then we'll only have ourselves to blame when she does something.
