I'd like to know...Is it in the genes??

After re-reading the last entry - I was thinking if the way Rob is, is because its hereditary?
How is it most of his family is the same way. I mean personally I dont care as none of them did anything to me, except for Rob. Now I'm the last person to toot my own horn or my family's for that matter. Of course being the big mouth, outspoken, rebellious person I am, I caused allot of drama and still can to this day.
BUT - my parents have stuck together for over 40 years, never any "nookie on the side" - my brothers, both actually, are in long term relationships, if not married. Stuck by their partners, never unfaithful, and I like to think I'm the same as I never have...until I was forced. Where as his family is the opposite, with the exception of the baby of the family. Rob is a spitting image of his older brother, in the sense of slaggin around. The difference is his older brother checked out that back of NOW magazine, where as Rob checked out the back of NOW, XTRA and countless other fag rags... He will/would deny all of this but again, I'd put him to the test and the outcome was always as I suspected, so deny all you want, you and I both know its true ;) - Is it that monkey see monkey do syndrome? Or is it lack of self respect? My mouth is more vile than I really am where as with Rob its the opposite, he doesn't come across, verbally as vile, but its his living that does that. His actions prove and show that. Maybe its something that's just instilled in him? How does one sleep at night with thoughts of things hes done? He must and if he doesn't he should hate himself for becoming the horrid person he is. I personally would hate myself, but, thankfully, I'm nothing at all like him. He is not one to be modelled after, at all. I always wonder if there is anything good to say about him and unfortunately, not one thing comes to mind. He doenst have a good heart as history would not be the way it was. He doesn't have a conscious as again, history would not be as it is. Trying to think of one redeeming quality in that slag is very difficult. As much as I am totally over him, no one has ever pulled on me what he did, so really where is there a good quality in him? Being a pothead couch potato slut is not a good quality, well not in my books. Being Miss priss by day and a holy whore by night isn't a good quality, not in my books, so what good qualities does he have? If anyone can answer that, you know how to get a hold of me, cuz I really would like to know.
