Yesterday  mom and dad were bickering again.       I comforted them separately for an hour more.      Everytime when they quarrel,they will call me and pour out their troubles .        Sometimes because of the slack business ,sometimes because of their emotional matters and other trival things in life .        Everytime I heard,I am so moved and painful,they think so much of us children that though they always want to divorce,they didn't ,for offering us a complete family.        I wish I could share their painness.       They are so tired ,both in pysical and mental.        I am so sorry for them.        I hope I could graduate quickly to make money to give them a better life.      And maybe,to encourage them to divorce.       Yesterday in the morning,I went to the Customs and vomitted a lot because of bussick and then got a heatstroke.          When I came back in the afternoon,I had an exam.      Then in the evening ,I went to take part in my training of Customs declarer.      I planed to tell them this tired day,on hearing their trouble,I quitted.        I think I shouldn't complain with them my trifling hardship.        I cannot let them worry about me.       I don't want to impose additional burdens on them.        I think I should talk with them about more happy things.       Compared with their pains,my  difficulties are slight.       But watching a bucket of dirty clothes that have to wash,I feel so tired.          Opening computer,I saw mom's message left for me.         I  am grieved.       Seems that she waited me to talk with her on Internet for too long .        She seems dreadfully disappointed  at dad.        Seems that their marriage have reached rock bottom.        But I was really too busy  to surf Internet,I am so sorry for her.      I know both of them suffered a lot in their unhappy marriage.
