Context: So , last night I had this insane dream that I was supposed to go see Rigoletto at the Met , but when I got there ( a little late ) my friend and I had separate tickets and were n't seated together . So I went walking around looking for a place to sit , and ended up as the overture started on the mezzanine level where there were these cafe tables . I know , you 're saying Overture ?
