Befriend her, show her a little attention too, and tell her you're gonna help find her a guy. Showing attention to her friends and ignoring her makes her feel left out. When she's with her friends is the only time she probably feels good about her self. Excluding her from the interaction while you interact with her friends makes her feel bad about herself. When she feels bad about herself, her guard goes up and she's gonna become an unstoppable object. She's fat, so she's already an immovable object, but when you ignore her you're awakening an unstoppable force. An unstoppable force + an immovable object = cock blocked. Be social and include ALL of the friends.
"What's the difference between us.
We can start at the penis.
Or scream I just don't give a fuck and see who really means it."
