I remember being told that my sister would come pick me up after school ... and I waited , and waited , and finally called to find out what was going on . They had forgotten about me , so my mother sent our neighbor to pick me up . I could tell that this neighbor did n't know for sure whether or not I knew what was going on , as she danced around the topic , and gently tried to tell me that everything was gone . I still remember how my room was arranged before it was all moved away .
