Surely not!

I'm not sure when or how it happened but at some point in the last few months I seem to have crossed an invisible line. At first I thought it was a random happening but it now occurs on a regular basis. Somehow, I have become a person for whom people relinguish their seats on buses.

Now I don't wish to sound ungrateful and I am very pleased that there are so many well brought up people around but it is a little unnerving. How can the energetic, youthful person that I am inside look as though I need to sit down?
