shaving heads

Yesterday my son and I had our hair cut with a shaver, which is normally called BARICAN in Japan. It was so nice that I felt comfortable when shaving hair with it. I guess that this feeling might be somewhat similar to that of one who loves gardening, pruning flowers and trees to get them in a good shape, and then cherishing them. So I've shaven our heads several times, repeatedly cutting and evaluating(not cherished yet). Through this process, I am getting some kind of skills to make it work better, and also our heads look better(At this point, I am not sure...I am trying to believe it). The more I get skilled, the more interesting shaving is. I am afraid that there is one possibility(risk?) that it became my hobby in the end.... Actually I don't have any time to spend on such things, though.....:)
