Your baby sister's baby has her second baby.
Your co-worker reveals she was born after you were licensed - you've been working longer than this college graduate adult has been alive. (Like Justmeinoz)
You realize you were born before touch-tone phones, color TVs, computers (of any kind), word-processors, ATM's, cell phones, smart phones, most medicines in use now, and a continuing list of things - what is "texting" anyway, and why do it?
