Mrs. Dennison

A tragic case. Her husband was a research scientist involved in wireless transportation of solid objects. His wife visited him at work with a can of his favorite chili, and interrupted an experiment.

She went insane after the accident, and was put in an asylum, where she spends her day pretending to measure curtains for her imaginary dream house, the one she shares with her husband.

Alas, he's remarried, and moved.
