Cheers guys.
I was seriously pissed off when I wrote that, so allow me to clear up any misconceptions:
Yes, my wife has cancer. She's had it ever since she was about 12, and it was treated. It's benign, although she goes for checkups regularly. It's not affecting her at this point.
What pissed me off is that I've got an uncle who has it seriously bad now. I'm not too keen on him so it doesn't bother me as much, but it is in the family. My mother's just been cured, so it's in the family too. Now my father's got it, and that's also in the family. What added to that was all the other family, direct or married-in, which also have it. It just seems to be that everywhere I look, someone's getting cancer. That's what pissed me off.
That said, I have a very strong history with my father (bad, not good), and he has never been a part of my life. Literally a few days after my 30th, I get a call from my half sister. He's marrying his girlfriend before he goes and he wants me at his wedding. Now I don't even know if this is what he wants. My sister has this thing where she wants a perfect family, and she sounded like she had a few drinks, so I don't really know what to make of it.
I shouldn't be put in this position. That's what's pissing me off.
