what is love ?

     yesterday , I visited some good friends ,of course we had a good and happy talking day. but , we must leave after 23:00 for we live far from there. so I left with a amiga .on the way home ,we walked on the roadside while told something ,suddenly  i found her face turned pallor.i worried her very much. i ask her what was wrong immediately .she said :

  'I am light in the head,I almost can stand now......'

  I buttressed her with my arm .And I knew she need  to have a rest at once. we found stone-chair to sit.After 20 minutes , She said to me :

    ' Bruce, I am very sorry for that, I am very tired '

    'I can see it , it seems you had  a bad sleeping last night ,  did you ?'

   ' yes, I almost fell asleep these night, I have feazed in the trouble loving , and I felt very upset.....

     She cried , I know affection hurt somebody so serious.but what make it happen ?is it amour-propre?is it blindfold feeling ?or others .

      This problem have hurt her long time , and she can not get rid of it .but I don't know why she is so spoony for such a man .I hear of her bf .he always  hurt her without any responsibilities which a bf need to have.
