Too shy to dance with girl I guess lol

Date: 6/26/2018

I was in my High school gym even tho irl I graduated 3 yrs ago. There were benches all around the gym just basic wooden benches. Students were sitting all around the gym and in the middle there was crowds of people some thing was going on. Beside me to my right sat a guy from my highschool named Harrison. He has autism and learning difficulty, is chubby, and can't understand jokes or social cues. ... To my left sits a cute girl I never knew but thought was cute named Danielle. There was music playing. I slouched down with my hands in my pocket and hood on my hoodie up looking forward. The girl looks at Harrison and says "hmmm well I really want to dance with somone want to dance with me. Then Harrison is like "uhhhhhhhh well I don't know how to dance and suck you wouldn't want me to do it." Danielle makes a sad face and turns back looking centre slouching like me, she looks disappointed. I don't show it but inside I'm very jealous and upset. Why would she want to Dance with him but not me? Probably because I look unapproachable and moody and boring. Then I consider for a moment telling her I will dance with her BUT, not only do I not know how to dance either... But it would also be really awkward and weird to start dancing to random background music in front of everyone. This dream is continued in my dream called Battlefield 4
