There's a man near the park who has been bothering me for the best part of an hour.
I first thought he was looking at his phone. Dark jacket, light trousers, standing near the path behind the houses.
Then he moved very quickly, stopped, and stood still again.
A few minutes later he did the same thing.
It isn't dramatic written down. A man walking badly. That's all I can honestly say.
But something about it was wrong enough that I kept going back to the window.
A woman came along the path from the other direction. She stopped when she saw him. I thought they might speak.
My phone rang before I saw what happened. It was Graham telling me the television is now advising people in parts of east Birmingham to remain indoors.
I've locked the back door.
I feel slightly stupid for writing that sentence.
