Well, this happened to me on my 17th birthday about a month and a half ago.
It was still during summer so I of course was spending alot of time with my friends. One Saturday, I actually have to wake up and go to this band thing that really sucked. Anyways, when I got home that night it was 4:30 am and I was wiped, and I went straight to bed. The next day I didn't wake up until 3:00 pm in the afternoon and I got bored and decided to call some of my friends. Well, I called all of them and they either weren't home or they couldn't talk to me. Well, all week I sat at home and did nothing because nobody would even talk to me on the phone. So the next Saturday on my b-day my parents left for 2 wks. Right before my mom leaves she says to me: "Jennifer, if your friends call today, just go with it." With that she left. Well, I had no idea what was going on and was feeling sorely bummed that nobody had remembered my birtday for several hours, before I get a phone call from my friend Terri. She tells me that she is going to take me to the movies and out to eat for my b-day. I was so happy that somebody finally remembered it! She said that she would be at my house about 10 pm that night. At 10 pm that night she showed up. I was so excited that I ran out of the house and to the car. I barely noticed that the car didn't look like hers or either of her parents cars. When I got in, Terri was excited too, telling me about what we were going to do and what we were going to see, when she stopped and started staring at me. She told me that my glasses were dirty and then she pulled them off my face and all of a sudden I heard "now!" A pillow was suddenly thrown over my head and something grabbed my arms and tied something over my eyes, and it was suddenly pitch black. I could hear Terri screaming something and doors slamming and somebody jumped in the driver's seat and peeled out of my driveway, tires squealing. Well, during the next 10 minutes I was thrown around, yelled at, held in place, subjected to Terri's screaming, and just about every other loud noise you could imagine. When the car stopped somebody opened my door and tried to pull me out, but I was wearing my seatbelt, so it didn't exactly work. My seatbelt was released and I was being dragged across rocky ground, when I decided to use all my strength and stopped and managed to get my hands free. I ripped off the blindfold, and stared at all of my friends standing there laughing at me! I about killed them! and then I almost cried, because I was so happy. they threw me a party with a cake shaped like a pair of boobs, that even jiggled. It was the best time of my life.
Okay, so not the best story, but the only one I could remember at the moment...
