Now, as duly elected class president, he would be mature, dignified, a straight-A student, a mover and shaker, friend to the principal, adviser to the younger boys -- in every way worthy of the beautiful Heidi who had just entered his life under the most unusual and romantic circumstances...
At least that was the original plan.
