An amusing encounter

Last spring, when we went to hear the Ring Cycle at the Met, there was a rather eccentric woman who shared our partial view box with us, and with whom we had the occasional scuffle regarding box space and the subtitle displays.  She would always arrive about 1 minute before the curtain, carrying an number of bags, and was frequently on her feet to get a better look at the stage. We found out she had seen all three performances of the Ring.
       When we got our tickets for the Tempest this fall, we ended up in exactly the same box.  We joked as we arrived, at least our lady friend won't be here.  At 1 minute before the curtain, she arrived.  Maybe she goes every night?
        Then, last night, as we stood up from our seats in Fisher Hall after the Mahler, there she was again, sitting in the seats right behind us!   It turns out she goes to orchestral concerts too!  (Edit:  She was there for Wozzeck, too.)
