Translation - English-Portuguese brazilian - See you later

The last sentence is one of those "untranslatable expressions" from Japanese...
Although its literal meaning is:
"You are tired (from having worked so hard)"
this expression is used all the time to mean:
Thank you / See you later / Have a good night / I respect you for all your hard work / etc., etc.
It's a very common social phrase, used to show respect for someone...

Ou cansada.
