Do you want to be my [business] partner? [This is a an exceptional example of the use of the verb 'to want' with modal complemetizer 'ke/ki' when the subject in the main and subordinate phrase is the same. It should have been 'Keris ser mi haver?', verb 'to want' + infinitive. This is a clear influence of the Balkan Slavic languages: Bulgarian and Serbian, most probably]
