Превод - Португалски Бразилски-Английски - Vivemos do Perfume de um frasco vazio

This sentence "We live from Perfume of an empty flask" doesn't make sense. Can someone explain? Thanks

It does make sense. Flask is a bottle.
We live from a perfume of an empty bottle.
I'm thinking about the meaning of it. To live because of a perfume that's in the bottle, but there's none in it... Maybe it means something sad, that the person isn't "living"...

Maybe it would be better this way:

"We live of the Perfume from an empty flask"

For me it could mean that someone feels that his/hers relationship of love is not good, but it wasn´t always like that. He/She has good memories but it is in the past, there is nothing in the present.

Thanks Borges, is better that way...

Not "live of"; that is nonsense. "live off" or "live by" would be okay.

There is a similar expression in English: "driving on fumes" meaning your car's gas tank is so empty that only fumes (odor) remain and you are trying to use every last molecule. Maybe because you cannot afford to buy more.

Now that it was edited according to a native English speaker's comments,("live by" instead of "live of" I think you can validate the translation, samanthalee...

Congratulations!
The greatest voting ever.

True...

thanks guys!
