Teen in the laziest form...Arrgh!!!!

Okay he used to be helpful, kind, considerate now oh no he is just to busy for that well we will just see about that. He went from being full of energy to being lazy all of the sudden he can not do his chores without being yelled at....It is driving me crazy and since spanking does no good or would do no good not to mention don't believe in it unless absolutely necessary then that leaves taking things away but that does not seem to work either so back to the thought box oh my brain hurts. will I survive the Teen Madness!
