'It's one of those days you talk about when they are babies. . . . "She will be in 1st grade when he is in 4th.' "

Facebook was full of pictures of big and little kids shyly grinning and of moms and dads writing "Look who's excited to start her first day of school!" and "Yes, that is a tie!" and "Where does it go? Feeling old!"
