A lot of the time that trait goes hand-in-hand with the other. The sister I speak of is both. She's never been generous with anything. And I could probably think of a few other people who fit the bill from my past...it's unfortunate. My other four siblings are (mostly) normal. At least they are positive people for the most part. It's always lovely that we can choose our friends. It's nice when they are part of your family already.
When my great uncle died (and he was the worst, just a jerk from the word go), I went to his funeral, and was that something.
He was very involved in his church, and I was expecting the preacher to do the usual platitudes, but he didn't. He laid it right out what a pure miserable old bastard he was, and then, all the people who spoke, they backed him.
His four kids by his wife trashed him, then his seven or eight kids by various other women around town dumped on him some more. It was a surreal service, but he reaped what he sowed. He was a terrible, horrible person, just seemed to hate everyone.
Remember when I mentioned the work my mom went to tracking down her FIL's long lost brother? He was the long lost brother, and it's why he'd been shunned by his family - everyone hated him because he was such a jerk. Stole, lied, cheated, abandoned his wife and kids, just an awful, awful person.
Good funeral, though, because it was an honest one.
