There are some we have to deal with ,even though we don't like them.Of course ,there are also some we try our best to avoid because of dislike.I'm not afraid of hardship,cerebrating,gossip and people of all walks of life that are hard to avoid meeting in social activities.However,the eight things below are troublesome businesses  which I think they are in the life.

1. Decoration：Decoration basically  can't give you a nice experience and none does so for me   because  you cannot get well controlled of it on the whole even though you have tried your best  and it is also difficult to realise what the decorator has promised to you.

2. Seeing a doctor：You have been  told by many people that it is rather important to know a doctor nowadays.In general, I can't telll which one does better for our health,seeing a doctor or bearing the illness.Even the doctor you get acquainted with can't guarantee his operation on you is safe.

3.Litigation：I think the average cost of litigaton is always higher than the one without litigation  ,even though I am a law-learner and once worked in the Politics and Law Department. It's hard to say that standing the business partner of incredibility makes you suffer more pain than standing the contact with the lawyer and judge.

4. Killing the cockroach：They are obviously tenacious than humans and always updating and upgrading.There is no chance for humans to triumph over them.My experience of killing them is almost the same as that  of killing the never-ending flies in farming families .

5. Helping friends' kids find jobs：My job is found all by myself ,so I have no idea to help others find a job,especially my friends' kids whom I consider to be with no expertise and I won't employ if I were the boss.What's more ,I insist that the youth even with good fundamental condition shouldn't be employed if he doesn't look for the job on his own.

6. Writing the acadmic thesis：I have once written some acadmic theses  with a hazy notion which arise more and more dislike in my mind.In addition,they must go through the review of "acadmic experts" and the modification after the review is more difficult to understand. 

7.  Back-door dealing：I feel ashamed at the back-door dealing by either sending gifts or giving a feast.Additionally,I hate back-door dealing and never do such a thing  but I 'm pushed to involve in it by my relatives and friends.

8.  Mediating the household dispute among my relatives or friends：In general , the problem among the kin is solved by affection while the one among strangers is solved by truth. However,the friends or relatives can't give in on the dispute and persist in his own reason . If you say A is right,B must be unsatisfied with you and vice versa.If you have to balance it ,you must be more tired than  the troublemakers.

I think ,we all have our own trouble in the life which is the one that we are worst at or dislike most or the persistent ailment of life.It often makes us be at loss in the way of life.
