Media notes
Duet. I silenced several intrusive noises during pauses in the calls, but did not alter the timing.
Observation details
Heard lower voice, higher pitch answer. Continuing near midnight, until illegal fireworks were set off nearby. Lower voiced call more frequent initially (i.e., not always answered).
