Frustration at work
A coworker has really been getting on my nerves. This isn't annoying salesperson--thank goodness (she's gone)--but it's someone who sits basically right next to me in our little "pod." At first, it was personality stuff, and now that I'm annoyed at those things, little mannerisms and "lower level" things are bugging me too. It's all going downhill.

Personality things:
-She is such a complainer. I now know I can't recommend any restaurants to her anymore, because she comes back to work after going to the restaurant whining about how much she hated it.
-She is overweight (probably "obese"--since it's over 30 pounds) but still goes to the vending machine several times a day and eats candy. Now that she's "on a diet," she complains nonstop about what she can't eat anymore. She has told us her goal is to lose 30 pounds by the middle of December, and if she does, her big "reward" is to go out for a big meal at Chili's. Hello!--that is not a "reward"--that's really a punishment since you'll be working against what you've been working toward for months.
-She'll turn around and start right in on some conversation she must have been having in her head and expect me to know what she's talking about. It's like she's rereading an e-mail I sent her yesterday or the day before or something, so she'll turn around and say something like, "Yeah, with that you're going to have to find out what the answer would be from Customer Service."
-She doesn't listen and always interrupts.
-She is annoyingly protective of and anxious about her 21-year-old son. She calls him all the time. She talks about how she can't go to sleep at night until he gets home, because she's so worried. She hears sirens on the street near her house and assumes it's because her son has been killed in an accident.
-The only change she is willing to go along with is one she suggests. I created a style guide for our department and did a reworking of all of our AutoText to update grammar, punctuation, etc. I also fixed consistency in spacing (some sentences had 2 spaces after periods, some had 1, some even had 3--I went with the Chicago Manual of Style, since that's what our company supposedly uses, and corrected everything to 1 space), and she is still complaining about that 9 months later.

Mannerisms:
-She talks weird. She halfway smiles whenever she talks (not bad I guess), so when she says her Ps (like in "park" or "apple"), her upper teeth touch her bottom lip to make the sound (instead of both lips coming together to form the sound).
-Whenever she gets up from her chair, she does this annoying little "grunt" thing. I know she has back pain, but jeez!

OK, and now it's time for me to do what would help me: begin praying for her. Anyone else have ideas?
