You guys are ****ing dumb. Poor chinny has a problem, dont be another one.
My dad is pretty much the same way, except not as bad. Your dad is probably very jealous of your success, that he never had anything like that, car stereos and such... His niche is working and saving moneyy to support his family, what he knows. Even if you can afford a house, hes so used to living on the edge all of the time that as you said he can't make the step up.
You have to play on his niche, step in his shoes. Always be interested in what his work is like, admire him for the work he does. It may **** to listen to but might help you get a better relationship going.
Worth a shot, better than knocking him out.
