For some of us, it happens gradually. Years pass. Our bodies soften, our politics shift, our children's feet grow bigger than ours. Then one day we catch our reflection in glass as we rush down a busy street, or hear words that seem to have escaped our mouth and ask, "Did I just say that?"
(That being, "Are you really wearing that?" Or, "If James jumped into highway traffic, would you jump, too?" Or, "You're going to catch a cold going out with wet hair!")
And we laugh, groan or shake our heads and wonder, "When did I become my mother?"
For others, though, no such grace period exists.
"June 6, 2003 -- D-Day! OMG! I'm my mother!" wrote Lisa Fosse, 49, of Columbia Heights. Fosse was one of many women who responded to our query: "When did you know you had become your mother?"
"It was a routine morning," continued Fosse, the mother of four girls. "But, when I looked in the mirror, I gasped. Oh, boy!"
Mary Simon of Montgomery, Minn., also had an "OMG!" moment. "One day I was changing the greeting on my answering machine and listened to the message for final approval," Simon, 49, wrote. "I heard my mother's voice and wondered how she could call and leave a message when I was working with the phone at the same time. Of course, it was my voice! OMG!"
Andrea Anderson, 29, and her sister, Joanna, 26, of Minneapolis, have both become their mother. "If my sister is already home when I arrive at our apartment, as soon as I get in the door I hear her yell, 'Woohoo?!' from the back and I yell, 'Woohoo!' as a confirmation that it's me. My mom has done that for years when we come home. It's like birds calling."
