Family traditions can be beautiful… until someone decides you’re the designated holiday bankroll.
That’s the situation one woman found herself in after years of sending a single, thoughtful group gift to her sister’s very large family – only to be blindsided by a request that would cost more than some people’s rent.
And now she’s wondering if she’s the bad guy for saying no.
When Holiday Generosity Meets Unrealistic Expectations
When Someone Treats Your Space as Theirs, the Damage Goes Beyond Objects
One of the clearest red flags in this situation is how quickly the roommate reframed her behavior as harmless. Moving personal items, using expensive skincare, borrowing sentimental clothing – especially something with emotional weight – all show a pattern of disregard.
But the deeper issue isn’t what she touched.
It’s that she acted like permission didn’t matter.
When someone enters your room without your okay, they’re not just crossing a line – they’re erasing it.
It creates a sense of vulnerability inside the one place you’re supposed to feel completely safe: your own bedroom. Locking the door isn’t an overreaction in that scenario. It’s a natural protective response.
In fact, mental health professionals often describe boundary violations like this as a form of low-grade emotional stress, something that builds slowly as you feel more and more watched, intruded upon, or exposed in your own home.
Why Her Reaction Says More Than Her Actions
The most telling part of this entire conflict wasn’t the borrowing or the misuse of items — it was the roommate’s reaction when confronted.
Instead of apologizing, she:
-
denied it,
-
laughed it off,
-
reframed private belongings as “shared,”
-
and called the OP the problem for wanting privacy.
That’s classic boundary flipping – making the person who sets a boundary feel like the aggressor, while the boundary-breaker paints themselves as the victim.
This is exactly why so many commenters called out “crybully” behavior. It’s a dynamic where someone behaves poorly, then claims they’re being attacked the moment consequences appear.
And, of course, she only became upset after she lost access to the things she felt entitled to.

Reddit’s reactions were unusually unanimous.
Every top comment points to the same truth:
The roommate never respected privacy, openness, or mutual trust.
Why Locking the Door Was Not Only Reasonable, But Necessary
Some people need reminders that “no” isn’t an invitation to negotiate.
The lock serves several psychological functions:
-
It restores a sense of security.
-
It signals a clear line that cannot be crossed.
-
It reduces anxiety about intrusion.
-
It prevents gaslighting by providing physical proof: “You can’t enter without my consent.”
In conflict-resolution terms, this is called a protective boundary, not a punitive one.
Even more importantly, the roommate forced the escalation by refusing to acknowledge any wrongdoing. If someone breaks your trust, you don’t rebuild it by leaving your door open and hoping they stop. You rebuild trust with people who want to be trusted. This roommate didn’t.
What This Means for Anyone Sharing a Living Space
This situation shines a light on three major lessons for anyone living with roommates:
1. “Shared” does not mean “everything.”
Shared spaces are shared.
Shared utilities are shared.
Shared apartments are shared.
Bedrooms are not. Personal items are not. Emotional belongings are not.
2. Permission is the foundation of healthy cohabitation.
Not “assumed permission.”
Not “you weren’t using it.”
Not “I thought it was fine.”
Only explicit permission counts.
3. Entitlement often looks like innocence… until boundaries get enforced.
People who feel entitled to your things often claim shock when you set limits.
They may even play the victim.
But that doesn’t mean you’re wrong for protecting yourself.
The Real AITA Verdict: Not Even Close
In nearly every interpretation – ethical, emotional, practical – the OP’s choice to lock the door was appropriate, healthy, and overdue.
The roommate’s behavior wasn’t “girl stuff,” as one friend said. It was:
-
intrusive
-
dismissive
-
disrespectful
-
and repeatedly dishonest
There is no version of this situation where the OP is in the wrong. If anything, she tolerated the boundary violations far longer than many would have.
At the end of the day, the lock isn’t a sign of broken trust.
It’s a reminder that trust is something that must be earned – not assumed.
