Hunters homework!!!!!!!!!

we are in the habit of sitting down and helping Hunter with his homework. yet sometimes he does not get it done. Yesterday was no exception. I told him to walk home from school clean the cat box and read his book for his book report until I got home. when I got home Hunter was no where to be found I called his friend but there was no answer. I called Rich and he said he would go look for him. I went outside to see if he might be coming and there he was with the friend that would not answer the phone. I told him to go in the house that he was grounded. we tried to explain the whole being responsible thing to him and explain why we were so upset. so back to the home work. I sat down got him started and had to run an errand and I told him ask dad for help if you need it I get home he was where I left him at saying he wanted me to help so needless to say no cat box cleaned no reading done and no homework either. what am I going to do with that kid.
