    We　asked　some　people　what　annoyed　them.　Here’s　what　they　said:

    I　don’t　like　waiting　in　line　when　a　shop　assistant　has　a　long　telephone　conversation.　When　that　happens,　I　usualy　say,　“Would　you　1.　helping　me?”And　I　don’t　like　it　when　shop　assistants　folow　me　around.　Then　I　say,　“Could　you　please　no　folow　me　around?　I’l　ask　you　if　I　2.　some　help.”Usualy　the　shop　assistants　say　they　are　sorry,　but　sometimes　they　get　3..　If　that　happens,　I　won’t　4.　to　that　store　again.

    I　get　annoyed　when　someone　talks　to　me　while　I’m　reading.　This　happens　to　me　al　the　time　in　the　school　library.　When　it　happens,　I　usualy　talk　to　the　　person　because　I　want　to　be　5..　But　because　I’m　polite,　people　don’t　know　I’m　annoyed.　So　they　do　the　same　thing　again.　Perhaps　in　the　future　I　should　try　not　to　be　so　annoyed.

 

Perhaps　the　only　test　score　that　I　remember　is　the　55　when　I　was　in　high　school.
The　test　was　the　final　for　a　course.　I　remember　waiting　anxiously　as　my　teacher　Mr.　Right　passed　out　our　papers　one　by　one.　It　was　a　rather　difficult　test.　I　heard　my　classmates　groaning,　and　I　could　tel　by　the　groans　that　the　scores　weren’t　looking　good.
Mr.　Right　put　my　paper　on　my　desk.　There　in　big　red　numbers,　circled　to　draw　attention,　was　my　score,　55!
I　lowered　my　head,　and　covered　the　score　up　quickly.　A　55　is　not　something　that　you　wanted　your　classmates　to　see.“The　scores　were　not　very　good,　none　of　you　passed,”Mr.　Right　said.　“The　highest　score　in　the　class　was　a　55.”
A　55.　That’s　me!
Suddenly　my　sad　look　didn’t　look　so　bad.　I　had　the　highest　score.　I　felt　a　lot　better.
I　walked　home　alone　that　day　with　the　low　but　high　score.　My　father　knew　that　I　had　a　big　test　that　day　and　asked　me　as　soon　as　I　got　home,　“How　did　you　do　in　your　test？”“I　made　a　55,”I　said.
A　frown（皱眉）now　stood　on　my　father’s　face.　I　knew　I　had　to　explain　immediately.　“But　Dad,　I　had　the　highest　score　in　the　calss,”I　proudly　stated.　I　thought　that　explanation　would　make　a　difference.“You　failed!”my　father　replied.“But　it’s　the　highest!” I　insisted.“I　don’t　care　what　scores　others　had,　but　you　failed.　What　matters　is　what　you　do!”my　father　firmly　said.
For　years,　my　father　was　always　that　way.　It　didn’t　matter　what　others　did,　it　only　mattered　what　I　did　and　that　I　did　it　excelently.
We　often　don’t　understand　the　wisdom（智慧）of　good　parents　until　we　ourselves　stand　in　the　parents’shoes.　My　father’s　words　have　carried　me　throughout　life.
