It has been a long day. Too many hours on my feet. I use a stick nowadays, mostly for reassurance as I am no longer as steady on my pins as I used to be. But, this evening, the ankles were not at all happy.
The bus was crowded; my heart sank. Then a nice young man stood up and offered me his seat. This has happened twice before, but I have previously declined. (Foolish pride - it's hard to give up the illusion of being an alpha male.) This time, I accepted gratefully.
And thus, another boundary is crossed. Getting old is no fun.
