text: my friend bought me sandals in brazil, how should i repay her? 1.  am i obligated to wear them?  what about during the world cup, because it has the brazilain flag on it? (go usa!) 2. am i legally bound to her in anyway? 3.  do i have to sleep with her now? 1.you should wear them yes, because you're friends 2. legally? no...ethically, no 3. haha! shes probably wondering if you think she wants you since she got the sandals. you aren't required to have sex...what a good friend you are
