volunteered

A has to do 10 hours community service to pass his civics class. So he mentioned that he would'nt mind working with kids helping them to read or do homework. So muggins here finds a volunteer network, easy as I had to do some for GScouts, sign him up for SAVY and find a local group. Then I fill in his forms for him, fax them to the group. receive the emails, look through the opportunities they offered, choose one, email back. confirm the time date and place, fill in another permit. Download a map to the place, take time off work to get him there on time. Drive back in peak traffic, not enough time to do anything at home before I have to go and fetch him and all this for 2 hours volunteering. Only 5 more sessions and he'll be finished. and so will I!
Last year I left it to him to organize the 10 hours he needed to pass PE. He didn't do anything so he got an F and had to retake PE this year. What's a mother to do?
