Weird things your co-workers do.

A lady in our office wears her dead grandmother's clothes. Polyester floral prints and pants that don't fit. I understand there's a grieving process but the grandma died over a year ago. My co-worker is in her thirties, single, and definitely on the spectrum. She does a fairly technical job and is good at it so no one has said anything. We just try to smile and keep her away from clients.

EDIT: I forgot to add, if she doesn't have anything to do, she'll pace back and forth in her ten by eight office to get exercise. She'll take three steps, turn around, and take three more steps. If anyone walks by her door, she'll stop and stare at them as if they caught her doing something bad. It's very unnerving.
