Way back when, my DD's friends thought I was a "cool mom" because we texted back and forth. Now that is old hat.
Yesterday we were talking on the phone (cell phones, of course) and she told me about a financial issue that will be hitting her soon. I told her that what she was facing was such a first world problem. She literally started choking ;-) She couldn't believe I knew that term, although it is apparently very common in her mid-20s age group.
So kudos to MMM and the forums for keeping me up-to-date on current terminology!
