Tender Is the Knee

My left knee has been a pain all day.  It keeps locking up on me, the kneecap sort of going where it wants to go, which means I have to sort of freeze wherever/however I am and try to work it back into place.  There's no pattern to the pain: sitting, going down stairs, going up stairs, just kind of standing around.  It's weird.  And painful. 

Thankfully, my lunch ameliorated some of that.  I present to you an example --- a perfect example, even --- of what I wrote about on August 14th.

A folded-like-a-taco potato chip.  Shaggy Tap in the back there looks interested, but he isn't a chips eater.  All the more for me.
