I've noticed a Western woman, wearing large, dark sunglasses, a snow-type knit hat, black puffer jacket, large backpack and Birkenstock shoes lurking around Exchange Square/ IFC mall for a couple weeks now and am finding her quite creepy. She just stands around, ALL DAY, every time I go out she is standing somewhere. Has anyone else seen her? She probably isn't up to anything but it just creeps me out to see her lingering around. So odd --- shudder.
