Another calendar year, me still here, reason enough, as the poster suggests, to be "in good cheer"?
The elderly lady sitting in silence with her companion may not look very cheerful, but moments later her face lit up with a smile and her eyes sparkled as other companions arrived. I know for myself that I can sometimes be inwardly at my most content when outwardly I may appear miserable. And conversely, I can sometimes be outwardly smiling and laughing while inwardly thinking, "I need to get myself away from these people and out of here." Inward contentment would be nice, for next year.
