I've got a near-constant group text going with the three best friends I grew up with. Over the years, that text group has evolved from Sunday afternoon messages of "How's your hangover?" to "How did the baby sleep last night?" I have other friends and a sister-in-law whose conversations have taken pretty much the same turn. We've evolved a lot throughout the years. There were times when three of us were mad at one of us. We've thrown bridal showers and attended heartbreaking funerals.
