time playing tricks.....

Three years ago I was pulling coats and hats off of my 12 month olds at ECFE playtime and a lady sat in the lobby with her four year old daughter. She smiled and said to me, "pretty soon you're going to be sitting where I am waiting for their kindergarten screening" I balked and said "not for a while!"....all of the sudden I'm the lady sitting with her almost four year olds for kindergarten screening. How did this happen so fast?!
