I used to watch Saturday Night Live and they'd do a sketch of these two windbags and think, "This has got to be an extreme exaggeration of those two." Then one day, I caught the actual show and realized they had it spot on. So if our generation doesn't fill our downtime playing video games, let's just fill it like our fathers and grandfathers did. We'll go to the bar, get drunk, come home, beat our women and children and put them in their place. We'll spend all day Saturday (and sometimes Sunday) on the golf course or "at the lodge" with a bunch of other miserable old men who will do anything they can to avoid going home and even making an appearance to the rest of their family.
There's a reason our mother's would use the line "Wait till your father gets home" on us; because he was never home and you knew that when he did finally get home, he would be in a piss ass mood and not want to deal with anything your little punk ass did.
I don't know about you, but that seems like a much better example to set for your kids than to actually be at home, eating dinner with them, interacting with them, and tucking them into bed. If you happen to be playing video games in between those things, then so be it. At least you're there participating in their lives and being more than just a "threat" in their eyes.
