I'm a college student now, with my first girlfriend and enjoying fulfilling days. One day, she decides to come back to her parents' house for a few days. I feel a little lonely, but I can't help it. I'm thinking about how to spend the night alone, when I arrive home and find her friend standing at the front door, holding a convenience store bag full of alcohol and snacks. For some reason, I'm having a drink with my friend at home, even though my girlfriend isn't home! Isn't this a bad idea? I wonder, but I'm still...
