In level 2 there are two sentences I don't quite understand: 1) from English to Spanish=Do you have hot water in your room? I wrote= Tienes (you) but Fluenz answer is Tiene (3rd person sing.) Similarly, Where were you yesterday with your colleagues? I used Donde fuiste (you past) but the answer was fue (again, 3rd per sing, past). Is "usted" assumed or what have I missed?
