You barricade yourself in your room, give us no more than yes or no for an answer, you are causing serious and unnecessary concern to your parents and you fail - and I mention this just by the way - you fail to carry out your business duties in a way that is quite unheard of.
Se atrinchera usted en su habitación, contesta solamente con sí o no, preocupa usted grave e inútilmente a sus padres y, dicho sea de paso, falta usted a sus deberes de una forma verdaderamente inaudita.
