Rather
you than me is an expression used when someone has something unpleasant
or arduous to do. It is meant in a good natured way of expressing both
sympathy and having a bit of a laugh at their expense.
If
you read between the lines, you find the real message in what you're
reading or hearing, a meaning that is not available from a literal
interpretation of the words.
A
real trouper is someone who will fight for what they believe in and
doesn't give up easily. (People often use 'Real trooper' as the two
words sound the same.)

If people are rearranging the deckchairs on the Titanic, they are
making small changes that will have no effect as the project, company,
etc, is in very serious trouble.
If
you give someone the red-carpet treatment, you give them a special
welcome to show that you think they are important. You can roll out the
red carpet, too.
If
someone reinvents the wheel, they waste their time doing something that
has already been done by other people, when they could be doing
something more worthwhile.
When
people, states, etc, threaten to use force as a way of getting what
they want, especially when they are unlikely to use force, they are
sabre-rattling.
If you rub salt in a wound, you make someone feel bad about something that is already a painful experience.
'Pour salt on a wound' is an alternative form of the idiom.
If
someone escapes scot free, they avoid payment or punishment. 'Scot' is
an old word for a tax, so it originally referred to avoiding taxes,
though now has a wider sense of not being punished for someone that you
have done.
A
searching question goes straight to the heart of the subject matter,
possibly requiring an answer with a degree of honesty that the other
person finds uncomfortable.
If
you tall the fall, you accept the blame and possibly the punishment for
another's wrongdoing, with the implication that the true culprit, for
political or other reasons, cannot be exposed as guilty (accompanied by a
public suspicion that a reward of some sort may follow).
