We had a similar problem. Our son complained endlessly about the difficulties of carrying his horn back and forth to school. A friend suggested we rent another one. We did and it has worked out very well. We keep our complaining, good-for-nothing son at school, and we rented another teenager to keep at home. This one makes his bed, mows the lawn, and doesn't complain, even though he doesn't get the horn during school hours.
