surprise elevator!

as the lift came down to my level, and the door opens, i saw a girl ready to exit it. but as usual, she was just like one of the many people who thought it was ground floor when it isnt. and when she realised that, she stepped back into the lift again.

but then she looked at me, and exited the lift anyway, turning left and walking fast as if she's walking to her friend's apartment.

did i remind her of a friend that also stayed on the same level of me? or was she just being weird?
