If I do, don't tell me what the mistake is; just say, "you're close," or something like that, and I'll try and figure out the answer -- which could be pretty entertaining in itself.
Ja kļūdos,  nesakiet, cik liela ir kļūda, tikai pasakiet: „esat tuvu”, vai ko tādu, un es mēģināšu izdomāt atbildi, kas pats par sevi  varētu būt diezgan uzjautrinoši.
