Pictured above are two significant women in my life. What you can't see in this photograph are their knees. Good job; no, they're not knobbly. Nor have they drawn smiley faces on them. But both pairs are, at this moment in time, not performing as they should. Normal service will, I'm sure, be resumed a soon as possible.
In the meantime I'd like to wish the young lady on the left a Happy Birthday.
