He meets this girl who is a friend of his cousin's girlfriend. She says he has a sexy voice. He calls her but says 'hi' and the conv. ends. They talk through FB and one day she invites him to the MORP (what the fuck is this?). He accepts and they go together, but it's kind of awkward when they're alone. They dance but it's also kind of awkward. She leaves her at her house and is going to say goodbye in a sweet way but her parents come out. She enters the house. He goes to his house, and messages her on Facebook thanking her for the night and hoping her parents are not that mad at her for coming late. TA DA.
That sounds kinda bad :P it's better if you read the entire story.
Stop being so awkward and just live your fucking life. You're too caught up on what others think of you when it really doesn't matter, you probably wont see 95% of your senior class for a long long time if ever, so either just man up or keep saying what ifs? Even if you did, who gives a fuck. Are you going to stay up at night thinking OMG THEY THINK IM WEIRD.
Worst case scenario is that no one likes you, but honestly it doesn't sound like it would change anything with you.
