Name changed as have told everyone about this IRL.
Doorbell rang at 2am. I was half asleep/confused and thought it might be an emergency so darted into the hallway and turned on the light before stopping and thinking, "wtf I'm not opening the front door at 2am to strangers".
So then I sort of hovered in the hallway waiting to see if the person would knock or shout "I need help" or something but instead I heard a man say "the light's working" and then nothing. By the time I got to the window they were gone.
AIBU to think they were probably burglars trying to see if the place was empty?
I can't imagine what else it would be about. It didn't sound like teens.
