看到一篇講需要的    "不是因為不需要就能夠放任離開  需要就留在身邊
所謂的需要  指的並不是有沒有幫助的問題"      那需要到底是什麼= =

I am not sure if I understand the title or the question, but to me the need is something from you, something you think of feel, then it is up to someone else to fulfill that need. So even though the need belongs to you, someone else help you to fulfill it.
