What is meant by a 'complex person' ?

You have a coworker in her seventies????

“Complex” can mean many things. OP. But “simple” only means one.

What she means is that she is threatened by this person and doesn't want you to associate with her.

Is that similar to "a piece of work"?

OP have you just been released from a bunker?

R1-There are two people in my office that are in their seventies.

Complex: not disposed to obvious patterns, not easily predictable, moody, a "dark horse", layered and difficult to read...

It's not always a bad thing to be a complex person, though often, as OP's co-worker seems to have meant, it has connotations of a complicated (more than complex in the sense of a richly layered person), a person whose potential troubles are not too far below the surface and best avoided.

-10/10

She's saying this person is nuts and warning you to be careful around her.

R1 Yes, she's retired and took this as a part-time retirement job.

R7 Thank you for the answer. Now it makes sense.

R8 I picked that up, I was just wondering why she used the word complex on her.

Nuts

Very Eccentric

Autistic

Narcissistic Personality Disorder

Borderline Personality Disorder

Asshole/Cunt

The possibilities are nearly endless.

Annoying but smart.

Interesting but crazy.

Hot and cold.

The answer is CRAZY. It's like calling an older ugly guy "distinguished." Or saying an ugly girl has a "good personality."

Your co-worker sounds like a socially graceful person who meant for you to infer what R9 and R13 said.

Your co-worker doesn't know the meaning of the word 'complex' or is trying to use it as some kind of code word to you. Nothing wrong with being a complex person - being a many faceted person. Maybe the co-worker doesn't understand the difference between an adjective and noun.

I had a Division Chief who used “complex” as a euphemism for colleagues who were a pain on the ass. Who knows, he may have called me complex to my colleagues!

You didn’t need to tell us your age OP, using the phrase “taken lunch together” told us all we needed to know.

"very complex" - She has many complexes.

She's warning you the other one is a bit crazy. If you're somewhat new to the job, be aware that the truth of that may be questionable. Some people get obsessed with office politics and like to get new hires on their side. If you've been there long enough to know the coworker telling you the info is reliable, then of course that doesn't apply.

Complex = BPD

Bless your heart, OP.

A pain in the ass.

Every workplace has at least one.

Psycho, disloyal, self-obsessed, indiscreet, strategically emotional, an occasional flatterer but moody and unpredictable.

....

8 outta fkin ten bitch. You ain’t fooling me. Who ain’t heard that expression before? Other than that, well written.

Thanks everyone! It makes it more clearer now. As I said in my OP, I don't know this other woman and I don't associate with her (unless I have to for business reasons), so I will be keeping my distance.

She meant the woman had more going on than a silly twatling who checks her phone while she's talking because of the twatling's inability too steer the conversation back to something others could enjoy, evidence of what others call an "asocial simpleton,"

So don't sit with her. Don't tell the other coworker what was said. And stick to your non-present virtual communications (whatever they are) and feeds to avoid others. They'll all be better off.

R27 is angry, while he waits for his breakfast to be delivered by Meals on Wheels. He hates when they run late, because his home health aid has to take him to his doctor's appointment - he has a full day.

Complex in this context means difficult to the point of trouble. Are you autistic? Stupid? What?

OP, you're old enough to know how to use a dictionary.

“She’s a fucking bitch.”

Hi guys. It's OP again. I was at Wendy's today and wanted to take a seat. There was a nice little table by the window but there was two Dollar Tree bags on the table. I asked the young ladies sitting at the next table if these where their bags. One replied, "Mind your own business buster, and also you're rude" I said "Please I would like to eat my dinner at this table." She said "Go fuck yourself, faggot."

What does "Go fuck yourself, faggot" mean exactly?

R32 is not the OP. He's a Millennial off his medication.

I knew a girl who was a 'complex person. ' but then she died.

R33 is OP, aspie, but no fool! Can't put anything over on him!

She's REALLY into show tunes

Mentally ill.

EXHAUSTING

Why didn’t you just ask your coworker what she meant?

[quote]You didn’t need to tell us your age OP, using the phrase “taken lunch together” told us all we needed to know.

And if I said I grabbed my insulated Power Rangers* lunch bag with a container of hummus and a juice box, and headed to my car in the parking lot to sit in the back seat all alone and 'destress' from the anxiety i built up from talking to people all morning, you would've guessed I was a Millennial !

*Disney Princess for the female millennials.
