@Jaqen,
Some of the previous advice is incorrect.
My questions are:
1. Any grammatical errors?
2. Is 'distinguish' a right choice of word given the original meaning?
3. Anything else that sounds off?
4. Does this sentence represent a well-spoken native English speaker that he claims to be? He often emphasizes that he's Korean only on the outside and he talks and thinks like an American.
1. Yes
2. No
3. Yes
4. No
The script is illegible because it was written in pencil a long time ago.
