     One of my longestrunning battles (战役)with my kids is about manners specifically about whether it's

necessary to send handwritten thankyou notes for gifts.I told my children it was a must so they have

continued throughout their teens to write the notes,but they always grumble (发牢骚)that I'm out of step

with the times.

      If a BabyCenter's survey is a guide,I'm not alone.A surprisingly large number of parents still insist

(坚持)that their children practice some oldfashioned manners such as putting pen to paper to say thank

you,and treating adults with respect.

      Among the reasons,the one provided most often by parents,according to BabyCenter's report,is that

they see so many badly behaved kids around them that they're determined to raise their children differently,and meanwhile,many parents agree that"the world is a more  freewheeling place,and they want to give their kids a stronger moral compass (道德的罗盘)to guide them".

      This creates a particular challenge for parents for the reason that they have to find a sitter,nanny or

other childcare providers who will insist on the manners they consider most important but the fact is that it

is very difficult to find the right person.

      Perri Klass wrote recently in the New York Times about her annoyance at a rude,demanding boy

Perri Klass wrote,"I do pass judgment"on kids with bad manners "and so do other pediatricians

(儿科医生)who do the same work as me" since rude kids make them wonder whether the kids' families

are moral.The whole "manners"concept (观念)might seem a bit oldfashioned,she says,until you accept it as a hotbutton childdevelopment social skills.
