Answer:
Annie Frank developed from a shy and lonely teenager into a lively, confident person as a result of her discussion and subsequent relationship with Peter Van Daan
Explanation:
Annie Frank was a lonely Jewish teenager who was hiding with her family in a secret attic from the Germans in Holland during World War 2.
On her thirteenth birthday shortly before World War 2 in 1942, her parents bought her a diary as a birthday gift. The diary which she named Kitty, became Annie's best friend and confidant where she chronicled the daily events in her life as well as her secrets.
