     I have had the privilege of meeting some very interesting people over the years. Some of these

people made a great impact on my life, my views and personal philosophy. Others I met had the

opposite effect because they represented attitudes, behavior and beliefs that were directly opposed

to my views on life and my feelings about the value of all people.

     One such person I met was a woman in her late seventies. She had been an active woman, raised

a family and had engaged in helping others, and developed her own crafts to sell at selected craft

shows throughout the year.

     When I met her for the first time, I couldn't believe that she was in her late seventies - I would

have placed her age more in her early sixties. After speaking with her for a short period, it was only

then that the conversation seemed to turn to age. And, it wasn't a conversation about the frailty (脆

弱) of age, or the aches and pains, or about pleasures lost.

     The conversation, instead, focused on her zest for life and all the things that she was in the planning

stages of doing. And, what she was planning to do wasn't about going to a seniors group so she and

her husband could go on a bus tour. What she was planning was an excursion (旅行) to Europe,

unaccompanied by any tour operator or taken around the usual sights by a local guide.

     She really impressed me a lot because of her zest for life; for an uncompromising view of the future

not in the least affected by her age; for the undying faith in knowing that there was a great deal of life

yet to be discovered and experienced and yearning for each new image, discussion, smell, cultural

uniqueness or experience.
