<human>: Can you condense the text into a few key points?

I'm a senior in high school. I didn't go to the homecoming dance, mainly because I didn't ask anybody. 

I was planning on going and asking a friend I'm interested in, but I kinda wussied out. She's a tall volleyball player (I'm 5'8", she's 5'10"), really cute and great personality. We talk pretty often and I even go to her games. I didn't end up asking because I was pretty shy (never asked someone to a dance) and the height thing really discouraged me (all my other girlfriends have been way shorter or around my height). Some of my friends said it was weird, others said go for it. 

Whenever we talked about homecoming, she always said she needed to a date, etc. I didn't know whether to take that as a signal or not. Also, my friend mentioned to her at homecoming (she went with friends, without a date) that I wanted to ask her, and she said she would've said yes :\ 

Now winter formal has been announced. Should I even try asking her? The height thing bothers me, I'm not sure if it's "normal" or not.
<bot>: Thinking about asking someone to winter formal, but she's taller than me. Is it weird/normal, or should I just not be bothered by it?
