Transition at Work

Today, one of my coworkers turned in her two week notice and another announced that she is pregnant. Wow. I understand why the first is leaving--the stability of our jobs here is still up in the air and the job that she is leaving for is a better fit--but it's still sad. She's always been very kind to me. And the coworker who is pregnant is the one I work most closely with, so I have 7-8 months to learn how to do everything she does now!! Ack!
