All you've got to do is to watch them, to time-sample the behavior, and say, every five minutes, you ask the question, "Is it good, or is it bad?"
Sve što morate je promatrati ih, uzeti vremenski uzorak njihova ponašanja, i recimo, svakih pet minuta, postavite si pitanje: "Je li to dobro, je li to loše?" Ako je dobro, kažete: "To je bilo baš super, hvala."
