Woke up naked in my bed, thinking that I should be at my sister's house and then I hear my mother yelling at me because I have puke all over my clothes but the thing is that my last memory was : me, my sister and her friends in a bar in my sister's town, which is 2 hours of driving from my house. So I call my sister so she can tell me wtf happened, and to make a short story, I have basicly puke in my sister's best friend car (and I had to clean it up the next morning), I fell down some stairs, almost got into a fight and at one point they lost me because I've decided to take a walk outside.
