I Want to Ask Out a Girl I Like

Yep and I've talked about it but every time I try and say hi it try to start a conversation with her I get too nervous and chicken out or when did have a small conversation I could show a smile because I couldn't focus on what was happening and when i said hi to her in spanish I just left the class after the bell rang quickly. Homecoming is less than a month and everytime i see her or see her smile it makes me smile. I have even talked more in class since I rarely do so I draw more attention but I'm akward.
