When the flowers arrived, co-worker loudly asked, within earshot of most of the office, "Ooh! Are those from HIM?!" She does this every year. I've never had an SO send flowers or gifts to the office.
It should be noted that co-worker is quite bitter about being single.
The above is from the original post.
I work in a cube-farm. There is a woman about whom I have posted before. She has never been married and actually stated marriage as a short-term goal in a business meeting.
She is in her mid-40s and fancies herself as the fashionista of the group. She also makes disparaging remarks about how other women in our group dress. She is insanely jealous if a male co-worker compliments a female co-worker for any reason from "You look nice today" to "Great job on XYZ project"
She also is nosy on the rare occasions when flowers have been delivered to anyone in our group. I.E. Very Nice Co-worker's husband works in the building next to ours. On their wedding anniversary, Very Nice Co-worker's husband brought her a small bouquet of flowers and a picnic lunch for the two of them to share in our outdoor area.
While they were outside having lunch, Judgemental Co-worker (JW) went into Nice Co-worker's cubicle and searched for a card that would have come if a florist delivered the flowers. When she could not find one, JW came to my cubicle and asked who sent the flowers to Nice Co-worker. I replied "I have no idea" (truthfully because I did not know there were
JW haunted our area until Nice Co-worker returned to her desk then JW pounced.
Once JW found out who and why regarding the flowers, she made condescending remarks "After being married for that long, the bouquet should have been bigger" and "What? He didn't get you jewelry, too? You need to train him better."
It seems as if the OP is dealing with a similar co-worker. Someone who is a gossip-monger and vicious if denied her supply while being vitriolic if someone has something she wants. It can make the workplace uncomfortable and, sadly, is usually a sign that the angry person is actually fearful that others have gotten her supply of the good things in life.
