I'm at work at the moment and I'm thinking about this sermon I have to do.

Struggle, struggle. I'm wrestling with the scriptures, as they say. I'm not sure what I'm going to say about it. It's a bit of work. Something will come eventually. At the moment though, it's a bit, blerr. I think I need to go for a walk. That's what I'll do. I'll go for a walk.

That might help.
