I make it two days before I give up and call Lisa, ten minutes before her shift. She doesn't answer the first time, so I call again. This time, she picks up, and her annoyed voice brings tears to my eyes.
"Hello?" that wonderful voice snaps into my ear, suspicious and guarded. She thinks I'm a robocaller.
"Hey, Lise." Somehow, I manage to sound normal.
"Ava? This isn't your number. Did you lose your phone?"
