Disappointment

Last year I was a long term sub. I had the best time and I got really attached to the other teachers and the kids! I loved the kids! I would have done anything for them. At the end of the year, my subbing job ended. I've been looking all summer, but none of my interviews have lead to a permanent job yet.
Last night the teacher I subbed for all year called me to see if I could do one more day for her. She was pretty sick with a cold and felt it would be better to stay home than getting all the kids sick. She walked me though her day and e-mailed me the plans. I was so excited about seeing the kids.
The automatic phone system however never called me. It called another person. I went in and when they told me, I had to give that person the plans. It was like taking away a child's favorite toy. I was crushed and so were the kids. Oh well.... something permanent is out there for me. T_T
