I'd like to ask about meaning these:
1. And how's it been with you and Jack?
We rub along OK.
Not rub each other up the wrong way?
2. I'm a glass half-full kind of girl.
3. I thought Australia would be nice (to fly there). But then I thought afterwards, what about my carbon footprint?
***** I am not a teacher *****
"We get along OK." I had never heard or read "We rub along OK."
"We rub each other the wrong way." Or, "Jack rubs me the wrong way." Up should not be included.
Carbon footprint refers to how much greenhouse gas production are you responsible for. She is wondering what the environmental impact of her flight would be.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
So, just to make sure I get this,
When someone irritates you, in the US and Canada, we say "He rubs me the wrong way" but in the UK, you'd say "He rubs me up the wrong way"?
