Quite often I hear this "harp" sound out in the hallway, like someone playing a chord or something on a harp. I thought it was when the nurses turned on some sort of program for the patients. I finally asked the nurses today about the harp sound. They said that sound happens every time a baby is born. I thought that was so cute! And, about five minutes ago, I just heard that sound. So today I think two babies were born.
