Need an oracle

I read Oracle Night, and again it was more about reconnecting with life than disconnection and alienation than I remember earlier Auster's being. I liked it a lot.

I'm supposed to be going to see my Gran today, but S claims a dodgy tummy. I don't want to risk a throw-up in the car or giving Gran a lurgy: but if I don't go today, I won't be able to get until Thursday. Hmmm. What to do? What to do?

It was Gran's 92nd birthday this weekend, you see, and visiting late in the week takes away from the birthday aspect. :(
