Who's with me now?

I love doing genealogy.  I eat, sleep, and talk genealogy anytime someone will let me.  I went to one of the Historical Societies today.  The staff is getting friendlier since they have seen me quite a bit lately, plus I am behaving.  Upon arriving today the parking was atrocious.  I found a spot but there was a car parked too far from the curb, so if I tried to get into this spot I would hit the car.  So I was trying to get in the spot my way when someone else came and moved their car.  Yes, I pulled in only to get the wrath of some elderly couple that had to wait three minutes till I moved my car.  Very impatient people.  I continued on my quest and was sitting at my table all alone reading a book, I hear this noise.  I couldn't see anyone around so I ignored it.  Then I hear another sound, okay, what was that.  When I heard it the third time I just figured someone was with me again.  They are at least friendly!  What better day than Halloween.....
