There was a range of emotions as students and teachers at Sacred Heart Academy in Stamford began saying goodbye Monday. Enrollment at the school has dwindled over the last decade, so now the all-girls Catholic school will close its doors this week after 84 years. On Monday, the senior class rehearsed for the school's last graduation ceremony. School officials say they are not sure what will become of the school and property. The pre-school and pre-k classes will run for another year.
