...annoy the h3ll outta me. My coworker, for example....a person whom I am sentenced to spend another 30 odd years sitting next to before I'm parolled able to retire. She giggles at EVERYTHING. She can carry on an entire giggle conversation:
Me: "I think I broke the stapler."
Her: <giggle>
Me: "There are 5 staples jammed in the opening."
Her: <giggle>
Me: "Do you have any idea how to get it unjammed?"
Her: "No." <giggle>
This can go on for hours, with her barely uttering any words and giggling like a toddler being tickled, even though there's nothing funny to laugh at.
