She noticed her phone buzzing on the table just as she stepped out of the shower. By the time she reached for it, the call had already ended. It was from a number she didn’t recognize, and there was no voicemail. Curious but not overly concerned, she shrugged and went about her day. Later that afternoon, the number called again. This time, she answered, only to find out it was a friendly reminder from her dentist about an upcoming appointment. Relieved, she made a note of the date and laughed at how much she had overthought the missed call.
