2 black square objects , floating , no noise at all , no lights, and ascended straight up out of view, one square larger than other

first saw objects quite low over trees, homes, and creek , stopped the car , got out to look and 2 completely black square objects in the vicinity of each other apparently floated straight up as they got smaller , but stayed at about a few hundred feet for a bit , one smaller than the other object, no noise at all whatso ever , no lights at all then vanished straight up , this observation first caught my wife,s attention and then i was driving and got out to witness also,
