What does 'no worries' mean exactly?
Because, I suspect that it meant one thing (apart from one actually having no worries, i.e.!) and then, is used generally and freely these days.
Me: I don't have a pen.
The other: No worries.
(I get it)
Me: Thanks a lot.
The other: No worries.
(I don't get it)
Me: Sorry about that.
The other: No worries.
(I get it)
Me: That was so nice of you!
The other: No worries.
(Eh?)
