Living Life Over
If I had my life to live over ... I would have talked less and listened more.
I would have invited friends over to dinner even if the carpet was strained and the sofa faded.
I would have taken the time to listen to my grandfather ramble about his youth.
I would never have insisted the car windows be rolled up on a summer day because my hair had just been teased and sprayed.
I would have burned the pink candle sculpted like a rose before it melted in storage.
I would have sat on the lawn with my children and not worried about grass stains.
I would have cried and laughed less while watching television and more while watching life.
I would have gone to bed when I was sick instead of pretending the earth would go into a holding patter if I were not there for the day.
I would never have bought anything just because it was practical， would not show soil or was guaranteed to last a life time.
There would have been more "I love yous" ... more "I‘m sorrys" ... but mostly， given another shots at life， I would seize every minute ... look at it and really see it ... live it ... and never give it back.
