Helicopter circling around my house? Kinda scared?

[AnimalGirl4]

Before going off and saying that I'm a baby or anything it's not my fault that I get scared easily... It's my sisters... She scared me even chance she got when I was younger.. So it's about 12:30 am and there is a helicopter circling around the area I live in... I don't hear sirens from cop cars or anything... What could it be?? I'm the only one up due to a very painful hurt ankle so I'm kinda scared... And no I didn't do anything
