Only after Obama had offered to drive his grandmother to work himself and it was becoming increasingly clear what a selfish lout the grandfather was, did Grandpa produce his trump card. The reason he wouldn't get his lazy butt dressed and drive Grandma to work was ... she was a racist!
As Obama recounts it, on Grandpa's third try at an excuse, he told Obama: "You know why she's so scared this time? I'll tell you why. Before you came in, she told me the fella was black. That's the real reason she's bothered. And I just don't think that's right." So I guess I'll be heading back to the sack now!
That makes sense. It certainly never bothers me when crazy white people harass and threaten me.
This is Obama's own account of what happened, which -- as anyone can see -- consisted of his slacker grandfather making a series of excuses to avoid having to drive the sole bread-earner in the family to work.
But Obama says, "The words were like a fist in my stomach, and I wobbled to regain my composure." (It was as if he had been punched by an aggressive panhandler at a bus stop!) And not because his grandfather's sorry excuse reminded him that he came from a long line of callow, worthless men, both black and white.
