Your imagination is a powerful tool, so you need to learn to curb it. Imagine she has a hairy butt, or imagine her sitting on the toilet taking a massive, smelly dump and grunting like an angry foul-mouthed sailor while doing it and scratching her butt after she's doing it because she hasn't learned to clean herself well. Imagine she just popped a huge, yellow zit.
Well, if this hasn't ruined it for you, then you should have distracted your mind away from it and taken her down from the high pillar your mind has put her on.
So smile. Look her in the eyes. And shake her hand. "Hi, I'm Ericho. What's your name? Hi Candance, nice to meet you." Take it from there. Remember to get her number at the end.
