                          In the German language there is a funny extra use for
                          the future construction: the expression of doubt or
                          an assumption. In these doubts and assumptions, there
                          is the grammatical form of future tenses but no time
                          mentioned.

                                  Er
                                    wird wissen, was er tut. = (I
                                    assume, I doubt that) he knows what he is
                                    doing. | 
                                    | 
                                 
                                
                                  |   | 
                                  Sie werden wohl das
                                    ganze Geld ausgegeben haben. = (I suppose)
                                    they have spent all their money. | 
                                      | 
                                 
                                | 
                           
                         
                         
                        This use of the future is rather common in spoken language, 
                        because with the voice (and even  the face) of the 
                        speaker it is much easier to get the idea of a doubt or 
                        a presumption. In written language the form used would 
                        most likely be: Ich denke, 
                        er wird wissen, was er tut. or something alike 
                        to make sure that the expression is an assumption. or: 
                         Ich bezweifle,
