"You are not working, but you are sitting here."
Translation:Ti nem dolgoztok, hanem itt ültök.
Because this is how Hungarian language works. :) In more details -tok suffix (sometimes actually -tek or -tök - depending on the vowels that are in the word...) is the suffix for plural second person, e.g. you in plural in verbs - always.
This is actually one of the main differences between Hungarian and Indo-European languages, that in Hungarian it is NOT enough only put the verb after the person, but you also have to adjust the verb to the person! But at least in Hungarian there is no difference between he and she, that drives crazy Hungarians learning foreign languages... :D
