Day 238: Put the period after embedded parenthetical comments.

To explain or elaborate on some point in your sentence, you might conclude with a comment inside parentheses. Consider this sentence.

“The new furniture will arrive on Monday (most likely in the afternoon).”

The entire parenthetical comment is embedded in the sentence. It is not a separate sentence. The period needs to follow the closing parenthesis. Simple. Here is another example.

广告：个人专属 VPN，独立 IP，无限流量，多机房切换，还可以屏蔽广告和恶意软件，每月最低仅 5 美元

“We upgraded our software (the new version is more stable).”

Although the parenthetical comment could be written as a separate sentence, in this case it is embedded in the main sentence. Thus, the period goes after the closing parenthesis.
