     Sitting is an art that isn’t getting passed along. People these days feel as though they have to be doing

something. If they are not working, they are jogging, or playing tennis or golf, or taking courses to

improve their minds or bodies-or they are parked in front of the TV. Sitting in front of the TV isn’t

sitting- it’ s watching.

     People used to sit a whole lot. You would walk down the street or drive down the road, and there

they would be, out on the doorsteps, sitting. You could go down to the store and sit on the bench out

front in the summer or around the fire in the winter. There were sitting benches out in the town square. At

the garage (车库), there were straight-backed chairs. There among the oilcans and tires and spare parts,

you could kick back and sit.

      Houses used to have sitting rooms, where the grown-ups would go after Sunday dinner. Mom and

Dad, Grandpa and Aunt Ruby would sit and digest chicken and talk about Aunt Ethel's illness, and how

well the minister did today. Outside, the children would play, and the afternoon would pass by in a

comfortable haze ( 悠闲的氛围 ).

    That sort of thing looks like doing nothing. A recharging battery (正充电的电池) doesn’t look as if

it' s doing anything either. Sitting restores your soul. If you want to enjoy a truly full life, don’t just do

something-sit there.
