     Since my retirement (退休) from teaching music in 2001, I have spent a good deal of time painting as an

artist. I actually began drawing again in the summer of 1995 when my father died, so perhaps I was trying

to recover from the loss of my father, or maybe it was just that it brought back memories of him. In any case,

I drew pen and ink animals and landscapes (风景画) much influenced (影响) by Kernel and St. John for five

years.

     For some strange reason, I had been waiting until my retirement to start doing watercolors again, but as

soon as I walked out of the school door for the last time I picked up my brushes and rediscovered Andrew

Wyeth, who quickly became my favorite artist. I had looked through all the art books I had on my shelves

and found his watercolors to be the closest to how I thought good watercolors should look. So I painted

landscapes around Minnesota for three years and tried out many other types of painting. However, watercolors

remained my first choice, and I think I did my best work there, showing my painting at a number of art

exhibitions.

     Art is now together with my piano playing and reading. There is a time for everything in my world, and it

is wonderful to have some time doing what I want to do. As Confucius once said, "At seventy I can follow

my heart's desire."

A. Learning to paint in later life.

A. had been taught by Kernel and St. John
