When I was younger, probably 9 or 10, we went to a church in Kansas City. I don't remember the exact year, but it was in the mid '90s as I was still in grade school. The church was located in a large storefront and was actually quite a bit larger than it appeared from the front. However, there were only two entrances -- the front entrance and the back door that used to be a delivery door for the offices that were once in that building. This was always locked no matter what.
My mother went to the church early one Saturday for a women's meeting that she had been planning. Since she was alone, she locked the door behind her and set about hanging decorations in one of the back rooms. She passed through the foyer several times as she carried supplies. She says nothing was out of the ordinary that day; that is, until she came out of the back room to find one of the church's folding chairs in the middle of the foyer.
She hadn't set it up and no one else was in the building. A chill went up her spine as she stood there staring at the chair that appeared to have moved itself. She says that she edged her way around it and unlocked the front door, slipping outside to sit on the curb and wait for the other women to arrive. She still has no explanation for this.
