Not funny at the time?

Annette Woodruff says:

I read through your notebook and enjoyed the humorous description
of your accident.... although I don't suppose you thought it was funny at the time.

Mark replies:

Actually, at the time I was in pain, but I did think it was quite funny. My first thought was "I fell down and I can't get back up!" My second thought is that now I have much more in common with my retired round dance friends than I ever wanted to! (Most of them are elderly.)
