lol at the comments in this thread. Mrs.Jones I think the answer provided on the link may be what I was looking for. Shirley, since you just have to know everything! The reason was initially a female coworker. I have a good relationship with her, very good conversations, even spend occasional lunch breaks with her. Nothing romantic or anything as she's a good 25 years older than me, we just get along. She works on a side of our floor that I cant see from my cubicle, but, when she makes her rounds her arms are always folded. Now one our directors, who's her direct boss, tells me everything, and this director from the conversations I've had with her is a little demanding and rides her a little bit.
This director is young, ambitious, insanely smart. You dont see too many women, hell, people her age achieve what she has at her age. With her young age however, I believe she lacks experience and maturity and its evident by how she compares the work output of this older woman with other young workers and students we have periodically doing rotations. So I know the older lady is a little stressed and maybe the folded arms are an extension of that stress. However, I've noticed other women that do the same and not just in my department, but others as well. It can't always be that it's because of of the air conditioning either.
