Wojtek: how did you guys wrote in exercise 5?
Filip: which group?
Wojtek: not sure, it was about a cat
Janek: you have to be more specific
Wojtek: when you had those free spaces, did you use vocabulary unchanged
Janek: no, you have to agree that with number and case
Wojtek: shiiit
Filip: gotta go, comparing answers stresses me out
Wojtek put a wrong answer in exercise 5 where the vocabulary should have complied with number and case.
