Miss Annie Rooney (played by Shirley Temple in the 1942 production named for the protagonist) appreciates the best things in life, like spring air, the language of flowers and books from the classic cannon. Mr. Marty White (Dickie Moore) admires her for the elegant young lady she is. I am certain he never let her go, especially after meeting her so suddenly. I imagine they married after three years of courtship, when Annie turned 17. I expect they settled on the Upper East Side, possibly in Sutton Place, and that Annie is stylishly prepared for social spring, her favorite season.
