I might be losing 2 sisters who I adore to a move this summer. Being an elementary PE teacher, I have taught these girls for going on 3 years. They are great kids and work sooo hard in my gym class. They are the fiercest of competitors but are well behaved and polite. How can I deal with this? I feel like my heart is breaking and I have just been so sad over the past week on hearing the news that this could be happening.
