"This is my room, not yours!"
Backstory: When I was about 8 or so, I lived in an apartment. It was relatively big, about 40 stories. My parents, my brother and I lived on the 14th floor, and we had a cool street view from our room. (we shared a room) We were just relaxing out on the balcony when the doorbell rings. My parents' room was closer to the door, so my mom went and opened the door.
OP: me
M: my mom
D: my dad
EM: entitled mom (there's a difference)
AM: apartment management
B: my brother
SK: strange kid
ANYWAYS:
*key rattling*
Out in the hallway, I heard someone cursing under their breath.
M: *opens door*
M: Can I help you?
EM: Excuse me, what are you doing in my room?
M: What?
EM: My room. You are in my room right now.
M: No, this is my room. My family and I live here.
EM: You are such a liar!
*EM pushes past my mom and sets her stuff down*
It was then when I realized the kid with her, who also comes in, and promptly drops his smoothie on the floor (we lived near a smoothie shop).
Meanwhile, I'm just watching the whole thing play out from the end of the hallway.
*EM approaches me*
EM: What are you doing here, you little turd?
OP: What's a "turd?"
EM proceeded to list every single alternate word for "turd."
Being the immature 8-year old I was, I began giggling.
SK: *laughing*
EM: HUSH! *slaps SK*
My dad had gone downstairs to get the management. He arrives back upstairs just after the slap happened. SK starts crying.
AM: what's going on?
EM: This b*tch stole my room!
I was super scared at this point and didn't really know what to do, so I just ran back to my room and closed the door.
B: What's going on out there?
OP: There's an angry lady yelling at mom...
B: huh?
B leaves room to spectate.
*Angry EM noises*
I don't really remember much after that, other than that the management dragged her out of the room and only THEN did she realize her room was on the 15th floor.
TL:DR EM refuses to admit that she is in the wrong apartment room.
