For several days I d noticed that our 24-year-old son,Tim,seemed remote,preoccu-pied.Whatever it is,I decided,he ll talk tome when he s ready.Maybe it had somethingto do with his girlfriend,Pam,though they gotalong quite well together.Finally one day when Tim came homefrom work for his lunch hour,he was nervous,his face drawn.“Mom,”he said sitting in our kitchen,barely touching the sandwich I d made,“Pain s pregnant.”
