What do you say to a girl that already knows they're beautiful?
zombiebacon:
Girls don't 'know' their beautiful. We know we're okay, pretty, maybe cute. But even the most conceited (seeming) girls don't know it. Tell her she's beautiful. Make sure you say "Beautiful" being called sexy or hot is only nice sometimes. Beautiful is what we like to hear the most
