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

I'm a junior in high school, and a new freshman girl just joined the marching band this year. Normally I wouldn't ever get to know her very well, but all of us band kids hang out together a lot. I really like this girl's personality, and being around her is great, but I'm not sure what these feelings mean, since I feel this way around friends sometimes too. I think I'm starting to like her, but if it ever comes to a point where I want to pursue those feelings, I'm not sure if it'd be "appropriate". First of all, I'm a junior, and she's a freshman. That seems pretty close to the cutoff for dating that's not "creepy". Second, it would break the "half your age plus 7" rule. She just turned 14 last week, so she's a young freshman, but I'm a young junior too; I turn 16 in a few weeks.
<bot>: I'm almost 16 (Junior), she just turned 14 (Freshman). I'm not quite sure if I actually have feelings for her yet, but if I do, is it okay to act on them?
