It was an emotional day for me when my six-year-old twins headed off for their first day of school. Four-year-old Andrew and I accompanied them to the corner to wait for the bus. When it arrived and the boys climbed on and waved good-bye, I could no longer hold back my tears.

"Don't cry, Mommy," said Andrew reassuringly. "Maybe one day you'll get to ride in a school bus too!"
