After an argument, a person says to the other, "live with it!"
Is that expression very impolite, rude? Is it similar to "leave me alone!" or is it worse?
Thank you, teachers.
After an argument, it is very rude, and means that you must endure the situation or agree to the speaker's opinion.

The phrase can be used in other ways however, as in explaining that a condition is not able to be changed. One woman to another: 'trucking firms just do not hire many female drivers, and we must live with that, I guess!'
I see, very rude.
Thanks too for the other use.
Great site.
