They don't know how to make friends, and have trouble even greeting people normally. In addition, they don't fit into ordinary social categories--they aren't students, they don't work and they rarely belong to clubs. Over time, they stop interacting with others, lose direction, lose the motivation to work, and even lose the will to live.
他們不知道怎樣交朋友，明明很簡單的一個問候，在別人眼中都成為「怪ㄎㄚ」的行為，加上他們沒有可供社會認同的自我定位──他們不是學生、不是上班族，也很少是社團成員，日子久了，這些年輕人漸漸失去人際互動、失去生活方向、失去工作動機，甚至失去生存動力。
