I could work in my studio without anyone complaining that I had n't taken care of an errand or stopped by the store for milk . If there was rumbling to that effect , I 'd just shrug my shoulders and say , " I ' m sorry , but I did n't have the car today . " And , on the whole , I ' m happy with my no - car - half - the - day situation .
