She turned on the A/C and opened the windows and could still hear it? Why didn’t she just turn the radio all the way up instead?
I can hear people outside of the car too when I turn the A/C on full blast and open the windows.
If she cannot reproduce the voices with you in the car, perhaps you better call the people in the nice white suits to come and take her away… ha ha ho ho he he… they’re coming to take her away
