Who was it? Did you inform them that their phone was fail? How did they take it?
My mom's cell phone is going on 3 years old and it's got such a shitty microphone now. I tell her every time she calls me and she keeps making noises about somebody setting up her hand-me-down Bluetooth headset. Riddle me why the woman with a degree in computer science can read a recipe to cook dinner, but can't read the instructions on how to set up her own toys.
