So, my dad has always been a providing dad first and everything else a distant second, not having anything that he really did himself for fun. us kids were his entertainment/source of happiness. i'm now a month away from 21, and my brothers 18, so while he still is a great dad, he doesn't have to do as much in terms of parenting. edit: he's 56. so lately i've been noticing a change. he actually went to a doctor to fix his sleep problems. he bought a motorcycle (not a harley either, a 1982 Suzuki GS1100E - FAST!!!!), and THIS is the weird thing: after a while trying to get my brother to quit smoking, it looks like he's adopted the "if you can't beat 'em, join 'em" philosophy and has started smoking himself. while that's not really BAD (i'm sure he'll get over it) i'm just wondering...why? so, has anyone gone through similar things? did they pass? is it just a realization that you can do what YOU want vs what's best for your kids now? do you overreact a little at first? i'm not really worried, but i'm worried that this is perhaps the tip of the iceberg?
