I agree with everyone saying do right by your ol man. You might think he's being unjust but he's just acting in a way that he feels will be best for you. As for me, my dad smoked with me from age 16 but i dropped out annd had a job. I smoke with my kid who is 17 and he voluentarily took summer school every year of high school and has earned enough credits to only do half days this year as a senior. Has a 3.0 and skips at least twice a week. I say either talk to him, deal with it or get out of the mans house.
