Dear All 與Dear all 的分別??

英文無人會capitalize "All" in that manner
就好似﹕ Dear readers, To whom it is concern ( no = Dear Readers, To Whom it is concern)
除非系個名﹕ Dear David, To Shirley, Dear Principal Yeung
Dear All = 錯﹐ 唔使 capital "all "
內容一樣都系﹐ 你唔可以亂 capital D 字。

Dear all, you all may not want to hear this but I have to inform you guys anyway.

唔會系﹕
Dear All, you All may not want to hear this but I have to inform you Guys anyway.
unless: Dear Principal Yeung, I am here to inform you about my love to Miss Ping.
