Firstly,talkingonlineisnoreplacementforface-to-facecontact—imagesreallycannotreplaceareal-lifesmileorhug.Accordingtoaparentingexpert,DeniseDaniels,communicatingthroughascreenmakesitmoredifficultforchildrentoconcentrateorshowkindnesstoothers.Asweknow,importantsocialskillsaredevelopedthroughdirectcontactwithotherpeople.Itistheseskillsthatenableustodeveloplifelongfriendships.

Secondly,theInternetcanmakepeopleself-centred—notthinkingofanyoneoranythingbutthemselves.Forexample,insteadofhavingproperconversationswiththeirfriends,somepeopleareonlyconcernedwiththeironlinepopularity—Howmany“l(fā)ikes”didIget?HowmanyfollowersdoIhave?—thoughweknowthatthenumberof“l(fā)ikes”orfollowerscannotcomparetohavinglong-termandrewardingfriendships.Inaddition,alotofthecontentpostedonsocialmediaisshallowortrivial.Postsaboutfunnycatimagesdonotnecessarilyhelpformmeaningfulrelationships.
