When I was younger, my mother left for work and warned us not to open the door because there was a rapist running around. My sister and I were hanging out in the living room when we see a white van pull up to our driveway and a guy get out. We hid in my closet and called 911, telling them there was a guy at our house and that it could be the rapist my mother warned us about. By that time he had left, but they sent over a cop anyway. We told him about the rapist so he drove around the neighborhood for us. :lol
I'm still not sure what the guy was doing, though. :lol
The second time was not so funny. While my mother and I were out, my sister and her boyfriend licked some otc patch (for the life of me I can't remember what it was) to get high. When we got home they were passed out on the floor. My sister's boyfriend was active, talking and stuff, but my sister had snot running out her nose and her lips were turning blue. One of the scariest nights of my life.
stealth edit: I also saw a homeless guy get hit by a car. by the time I got through there were already ambulances there.
