When I was still a child, my parents and I used to go to my paternal
grandfather who lived on the east side of Detroit (we lived on the
northwest side). He lost his wife in the early 1970s, so it was
important we visit. We would come each Saturday, and stay the whole
day--much to my chagrin as a young, playful child (old people's homes
are so-ooo boring

!).
By the time we headed home, it was often dark. And we often passed Mount
Olivet cemetery. Passing the cemetery used to bother me, especially
after dark. But I soon got used to it, thankfully. But this one time we
passed at night, I saw two cloaked figures in the cemetery. They looked
perhaps like two nuns I thought, but I didn't say anything at the time.
And they looked like they were standing by one grave, just gazing down
at it mournfully.
The street we were on was fairly crowded, even for night. So I was sure
other people must've seen it too. But when I brought up the subject
later, my mother said that it was impossible--no one would be in the
cemetery at that time of night. I asked other people and some of my
friends and neighbors, and they agreed too. No one would be allowed in
the cemetery after dark. So who were these two mysterious cloaked
figures then? I wonder to this day. (BTW, I presently don't believe in
an afterlife--but ironically still love ghost stories.)
