While I was in the hospital I learned I have a flank. I took Anatomy in college and got an A, but I swear, I never heard that word applied to humans. In the butcher shop, yes, but not out of the kitchen. I kept pointing and nurses kept saying, "Pain in your left flank?" I felt like a baby learning body parts. (Where's your nose? Theeeeeere's your nose!)
Did I tell you I celebrated my birthday in the hospital? But it's a good thing I did because, if I'd stayed home, it might be another 68 years before I learned I had a flank. At least I know I have a left one, presumably a right one too.
I don't know what I'm going to do with all this knowledge.
