Oh dude, don't get me started. This one time, I was out drinking with my best friend, another friend, my best friends' sister and his girlfriend. I was totally in love with the sister, but she didn't love me back. So I was kinda depressive the last 2 years. But back to topic here. So we were out drinking, and I got totally smashed, so I went up to her, fell on my knees before her, started worshiping her like a goddess, kissing the ground the walked on, etc. I don't remember this, but my best friend told me afterwards. So now, she doesn't even want to talk to me. THAT'S what I call epic fail. But hey, to see it positive, now it's easier to tear her from my heart, and concentrate on this girl I met last week which is just like me, when it comes to character traits, and seems to be interested in me.
EDIT: From this day, I owed to never drink more alcohol than the "necessary" one shot I have to drink with the girlfriend of my best friend on her birthday. Or as she said:"If you don't drink vodka with me on my birthday, we don't know each other anymore."
