Today I went to the bank to deal with financial stuff. The guy there who took care of me remembered Jack as soon as he saw the death certificate. And he was, of course, saddened and shocked at Jack's passing. At the end of our business there, he told me that the word Jack frequently used to describe how he was doing that day was "groovy." Or sometimes "groovitational." (That was one of his favorites I think.)
And that kind of sums up Jack's attitude on life. He was always "groovy." He always concentrated on the positive, not the negative. I don't know how he did it.
