In terms of meaning, it is as the others have said. However, the "impersonal" version should say: "Thanks for reading." ("Thanks for your reading." is equivalent to "Thank you for your reading.")

There is no literal translation as it is not used by English speakers.

"about face" means "turn around 180 degrees" it can also mean an abrupt/drastic change in thinking.

"我舍不得你走" can be (similar to what Bonnie said): "I can't bear the thought of you leaving," or "I can't bear the thought of you gone." "我舍不得花掉100块钱" is closer to: "I'm reluctant to spend that $100," or, if it's spending on something specific: "I'm reluctant to spend $100 on that."

there is probably no direct translation, but we can sometimes describe it with: "class" or "elegance", sometimes both! ie. "She is a beauty, but unfortunately she has no class."

Eventually the Britain Empire formally recognized the independence of United States. (I'm no history buff, but I believe UK was not in common use until after Great Britain's union with Ireland in the 1800s.)
