Where is the subject of the sentence ?
eg:-(--) have received Mary's letter .
As seen all 4 responses asked you about the "subject?"

Whether you possess all the letters:-the possessive case(grammar), or throw away,you can speak/use the same sentence.

來來去去都係同一個人問......奇怪的是仍有不少英文高手陪佢癲?

(補充一點, 答得多果個唔一定代表係高手呀)

係 ! but haven write down the subject : I

陪佢玩都唔緊要，最離譜係佢竟然多次 delete 我的帖，咁我先唔知佢想點～

係。不過前面要加翻個subject，即係例如I have received Mary's letter .

係, 不過呢句少左 subject, 要補返~~

呢條友已經成功玩死雅虎英文知識，仲有咁多人同倍佢玩。

封信宜家喺唔喺你度都可以講呢句。
