Person A got into a huge argument with one of the grad students in our lab today, it was bad, bad enough that another grad student had to step in and tell the Person A to back off in an unfriendly tone . In addition, I definitely noticed there were a lot of verbal "clashes" between Person A with two undergrads and another grad student today during group meeting, I felt like I was watching a drama TV show LIVE.

If there was a direct threat to me, which have already happened before (three times), what would be the best way to handle it? call the cops?

I checked out the center's website the other day and it seems like they have a link where I can submit a ticket anonymously, and I have told my PI that I didn't feel comfortable to be around Person A late at night in the lab due to previous encounters. I don't need this kind of stress, research is stressful enough.

This is completely uncalled for. I was simply asking advice on how to handle stuff like this because I have never experienced it before. If I was truly an awful person and want to use this against Person A I would have complained to the departmental chair already or filed a legal case against Person A.

Person A has been using school's mental health support and that is where Person A got the antidepressant prescription from. It has reached to the point that everyone in the lab started ignoring Person A's existence .

I do not know, but I have let my PI know that I didn't feel safe to be alone with Person A because Person A has made many gesture that symbolize choking someone and stabbing.

Person A told one of the people in my lab two days ago so I don't think it's just rumor, stuff like this is pretty serious. I do not know if my PI knows about Person A's mental health. All I know is that Person A often to "snap" for no reasons and make it very uncomfortable, intense for everyone in the lab.

Just found out Person A attempted suicide recently, and Person A is currently on antidepressant. Here is the catch, Person A is very unreasonable, argumentative, rude and like making unnecessary, hostile comments for no reasons. 9/10 of people from Person A's cohort class, and on my floor dislikes Person A, I found out a very good first year student did not apply my research group because he did not want to deal with Person A. Person A is very intellectual and knowledgeable, however, Person A likes to "lecture" people, including upper-level PhD students and my PI. I had gotten into many arguments with Person A before and have considered legal action against Person A because I have evidence to prove that Person A purposely contaminated my sample, but my PI stopped me. My PI recommends me to avoid any confrontations.

Oh hell yes Ain't nobody got time to play nice. I usually try to walk away before I say something nasty back, or something I know would "hurt" their feelings severely, I'm a Scorpio. There is a difference between being passive-aggressive and being a fxxking bully, and if someone is straight out rude and disrespectful I make sure to call them out during the group meeting or in front of the PI. I love drama....

Yeah, my friend and I always try to find reasons to get out the city on weekends, or go to museums or movies...just so that we can pretend we have a "normal" life style and aren't workaholics

It is a website for personal finance and budgeting. I've used it for over 4 years now and love it. One of my summer resolutions is to be able to stick with my budget on "food" lol

I don't like her personality, she's pretty dark and two faced and my coworker thought so too. She always talk/act differently whenever our PI is in the lab. Anyways, I'm not the only person found her annoying and she hasn't even started grad school yet.

Oh goodness. I mean she would ask my PI and my coworkers questions like, "should I aliquot out my sample into 50 tubes or 100 tubes?" "should I spin down my sample?" "should I read more papers on xxxxx?" I was like, gurl srsly? you gotta go!
