This happen on an uneventful day when I would go out with my neighbor to run some errands.
I went with my neighbor Mrs. Linda to her doctor appointment. I usually walk out of my house and lock the door. Then I would walk across the street to Mrs. Linda's house. Then I proceed to knock on her front door or sometime I would let myself in her house. But I would announce to her by saying " I'm here or it's me, Linda." And I proceed to help her in any way I can. I usually would help walk her to her car and once she is in her car on the driver side. That is when I go back in her house and get her wheelchair and take it outside to her car trunk and put inside. Then I will go to the passenger side and get in the car put my seatbelt on and close the door and then we drive off.
Finally we're at the appointment place. I would go out of her car after it's parked. And then go to her trunk and get her wheelchair out for her because Mrs. Linda has limited mobility. And she would get out of the driver seat and close her door. And walk towards her wheelchair and then I would be pushing her to her appointment area.
After her appointment, while walking back to her car. I would be so preoccupied in my own thoughts. And out of the corner of eye I would see that sparkling light that come and goes so quick every time. I repeat my same duty in helping her get back in her car and start the same process over. And again the same sparkling light would come and go.
Still to this day, I still do not understand why I keep seeing it every once in a very long while.
