Wish I was more social irl UGH >:(

So today I was at an event and saw a girl wearing a cute my melody and kuromi shirt and I had my fluffy my melody purse so I wanted to compliment her and become friends! and I went over and told her and we became best friends. In my head. In reality I glanced at her once or twice and waved at her when I gained confidence and she wasn't even looking </3...sigh. then once I saw a cute guy and really wanted his number, we kept looking at each other and I waved and he smiled. My family left before I could gain confidence and talk to him...</3. but online I'm extroverted as hell...
