I am not sure what kind of help you are looking for, but here it goes:
Well enough to come and go, especially after an illness. For example, I'm glad to see you're out and about again.1-out and about
It is a bit archaic. More often used is ''up and about'' meaning someone is active again.
Use this expression to say that you have no idea where are you, or when a place where you are is any place lacking population.2-in the middle of nowhere
Something or someone that causes annoyance, a source of unhappiness...3-pain in the neck
E.g. Ah, Mike is such a pain in the neck with his stupid questions.
Expressions like ''pain in the ass'' or ''pain in the butt'' are more often used, and ''pain in the neck'' comes as a more polite way to say the first two.
curious (or funny or interesting or odd or strange) though it may seem; "curiously enough, he didn't recognize his old friend"; "interestingly enough, America is now dependent on Africa for a large part of its oil"; "funnily enough, the ones I thought so ugly were the ones that sold out first"; "oddly enough, he hasn't mentioned it"4-funnily enough
This should cover all of them...
This is not an expression(idiom). It really means SOCIAL SITUATIONS, as far as I know. Maybe it's some kind of new slang...6-social situations
To get in a condition in which something can be clearly apprehended or perceived. To concentrate on. To pay a huge attention to something.7-focus on
I am not sure this is an idiom too...8-well-practised lines
Will this help?
