I (我) 為何要大楷？

因為i是一個單字母，小楷i是用作1, 未完成的課程，用大楷I，是讓人明白這I是我的意思。但you,they但，這是一個詞，不是字母，所以不用YOU/You。

As English Language is somewhat derived from German, it may be the reason why 'I' should be capitalized. In German, I = Ich and that is an example of word inflection.

Because I (me) is proper noun as same as a name... that's all.

因為(I)係大 teacher講

Because your teacher say : You will write 大楷.

因為要突出係我
