Referred to foreign people who leaves their natal country for many circumstances (jobless, war, famine, etc), to live lonely or with their family, seeking better situation.

While much of this song focused specifically on the children of American soldiers and Vietnamese women, these lines extend that message of acceptance to marginalized people the world over.

The line “They wanna sing all night long” could refer to how the people remain hopeful even in the face of hardship. Night and darkness are common analogs of despair and hardship. Singing is often a joyous activity, but here also refers to the pleas of these people for acceptance.
Looked at from the opposite angle, it may not mean that they are remaining hopeful. The song they are singing, much like the “Amerasian blues”, could actually be one of despair.

A semicolon (;) is used to connect two independent clauses without the use of a conjunction. It is essentially functionally identical to a period, but the clauses should be “closely related.” (Super helpful, I know.)

The playground was next to the school; the students would often go there during lunch.

This is where this stuff gets a bit tricky. These are some general rules. For a more in depth discussion, refer to Purdue OWL’s guide.

Punctuation always goes inside the closing quotation mark for dialogue:

• “Hello,” said Dave.

• Dave said, “Hello.”

• “What?” asked Dave.

When a quote ends a sentence, if it closes with a period, the period goes inside the the closing quotation mark:

• Hobbes referred to life as “solitary, poor, nasty, brutish, and short.”

When a quote ends a question or exclamation that is not in the original quote, the punctuation goes outside:

• Why did Hobbes refer to life as “solitary, poor, nasty, brutish, and short”?

• Hobbes referred to life as “solitary, poor, nasty, brutish, and short”!

Semicolons go outside of quotes:

• Dave said, “Hello”; he turned to face me.

• Hobbes referred to life as “solitary, poor, nasty, brutish, and short”; he was a bit of a pessimist.

When using quotes within quotes or dialogue, the same rules apply, using single quotation marks as necessary:

• “Hobbes referred to life as ‘solitary, poor, nasty, brutish, and short,'” said Dave.

• “Why did Hobbes refer to life as ‘solitary, poor, nasty, brutish, and short’?” asked Dave.

• “Hobbes referred to life as ‘solitary, poor, nasty, brutish, and short’!” shouted Dave.

• Dave asked, “Why did Hobbes refer to life as ‘solitary, poor, nasty, brutish, and short’?”; he wasn’t familiar with the man’s work.
