I am no longer needed

to walk Ms. K to school. Today she asked me to drop her off in the drop off driveway. I told her we would park and walk one more day and she agreed. As we were walking she asked me to stop at the front gate because she could walk to rest of the way by herself. I was so not expecting that today. It's only the sixth day of school and she already wants to walk by herself. I called Scott at work an told him my heart was broken when she told me she didn't want me to walk with her. This is progressing way to fast for me.
