I was about 15 minutes from finishing the night shift at work when there was a massive crash on one of the windows in the office so I get up and go to check it out. Someone has thrown quite a sizble rock through one of the windows on the front of the building. This is made especially weird because I'm working in the industrial district at 11:30 at night with none of the other businesses open. I go back to my desk, put a quick call through to security to let them know and decide to head home. As I'm leaving the building I'm freaking myself out about it more and more and end up running to my car, getting in and taking off. I'm almost home and I've started to calm down a bit when I realise that I didn't unlock my car when I got in. It had been unlocked the whole time. I do a quick check with my hand in the backseat for any possible murderers that might be hanging around there but there's nothing there.
Fast forward 30 minutes: I've called a friend of mine who says he is out drinking so I decide I'm going to join him. I jump on my bicycle and start riding over. I'm doodling along the road on my bike, it's a nice night and I'm in no big rush, just enjoying the moonlight when I hear someone riding behind me. I straighten up and stick to one side of the road. He passes me really slowly and, when he is right beside me, he shoots me a smile I can describe as purely fucking insane. I kind of flinch and am taken aback as he rides on. That's when I realise. He is riding my mom's bike.
Needless to say, I sprint the fuck home. When I get there, sure enough her bike is missing and one of my car's doors is open. The back left one. I was driving, and had no need to open that door.
