I told T about this thread and about how I wrote this just before he emailed me to say he was ill (but didn't cancel). He said it would have been pretty weird if I had written this then 10 minutes later he had cancelled.
I said if this thread had those kinds of powers, I would probably write something different. He asked what I would write, and I said I would think about it. Now I've thought about it:

"If I were your Dad, I wouldn't have let those things happen to you".
