     It was the first day of school. I stood up to look around when a gentle hand touched my shoulder. I

turned around to find a little old lady smiling at me. She said, "Hi handsome. My name is Rose. I'm

eighty-seven years old. Can I give you a hug?"

     I laughed and said, "Of course!" And she gave me a big hug. "Why are you in college at such an age?"

I asked.

     She jokingly replied, "I'm here to meet a rich husband, get married, and have kids and then retire and

travel."

     "No seriously."

     "I always dreamed of having a college education and now I'm getting one!"

     We became friends at once. Over the course of the year, Rose easily made friends wherever she went. She loved to dress up and she was happy with the attention given to her from the other students. At the

end of the term we invited Rose to speak at our football banquet(宴会). I'll never forget what she taught

us in her speech.

     "We do not stop playing because we are old; we grow old because we stop playing. There are only

four secrets to staying young, being happy and achieving success. You have to laugh and find humor

every day. You've got to have a dream. When you lose your dreams, you die. We have so many people

walking around who are dead and don't even know it! There is a huge difference between growing older

and growing up. If you are nineteen years old and lie in bed for one full year and don't do one useful thing, you will turn twenty years old. If I am eighty-seven years old and stay in bed for a year and never do

anything, I will turn eighty-eight. Anybody can grow older. That doesn't take any ability. The idea is to

grow up by always finding opportunity to do productive things. Have no regrets(遗憾;后悔). The

elderly usually don't have regrets for what we did, but we regret for things we

did not do."

     At the year's end Rose finished the college degree. One week after graduation Rose died peacefully

in her sleep. Over two thousand college students attended her funeral to honor the wonderful woman!
