25 year old semi-hikki here. Parents' house is a huge old 5 BR house. The house is surrounded by huge trees, and squirrels run around on the roof and branches scrape across the outside walls which is terrifying at night. Lots of big ground floor windows, so it wouldn't be hard to break into.
Not a fun place to be at night when the parents are traveling. I keep a knife in the drawer and leave a nightlight on.
