She is walking out there.

When you don't expect to see something and suddenly bump into it, you're startled and somehow frightened.
In Toronto, I have seen many old Chinese who don't seem like it, but they are about 80 -90 years old. By the look, many of them seem to be much younger. However some are really really old with deep wrinkles and bent back. We sometimes say they are at least a 1000 years old!
This one is one of those. Apparently she is staying with a neighbor's of ours. She is too old to walk outside so she does that in the corridors. Successfully she has been able to frighten me at least three times. Imagine coming out of the elevator in a rush and just bump into someone like her, with eyes' magnified a hundred times behind her glasses. It's like one of those scenes in Hitchcock 'sfilms where most of the horror comes from a simple normal figure with a horrible music on it. Or you feel Yoga from Star Wars is standing there and says " Maybe the force be with you".
