Just read a short story that I really liked. A bunch of quilters were discussing the possibility of a ghost. One of them got scared and left. One of the remaining quilters admitted that it was she who picked her sister's stitches out at night after everyone went to bed - not a ghost. Then one of the other quilters revealed that the stitches came undone each night after the former stitch-picker moved out. She was unbothered, saying that if any spirits haunted the house, she was sure they were benevolent ones.
