Second son went off to college the same day our oldest came home from volunteering at camp for a month.  It will feel very strange just having our youngest home after our oldest goes back to school. Love having our oldest home!!!!  I missed him a lot!Well, now I know why T-Man drug tested negative on the hair sample that picks up a 120 days worth.  I also understand that the testing doesn't pick up everything (in this case the pot he tested positive for on the urine sample) and that's because his choice of substance has been alcohol.  At least that is what I read in his instant messaging.  His girlfriend (who we only met once.....but not introduced as his gf) broke up with him because of his substance abuse.  He told her that he only tried one drug this summer and that he's only drinking.  We have never seen him obviously intoxicated but he is belligerent,  surly, disrectful etc.....and this is new.  So......I know it doesn't matter what he's doing ........but I don't know how we prove a drinking problem.  I understand there is a new test for drinking....but not sure how it works.
