An acquaintance of yours asks why you act so strangely around her. She seems a little hurt, and is worried you hate her or something. And the truth of the matter is that you have… well it wouldn’t be right to call it a crush, but you find her very beautiful and have been worried about making a fool of yourself. And it isn’t your intention to harass her or pursue her in any way, you’re not even looking for a relationship or anything right now, you’re just nervous around her for basically no reason, and she’s noticed and she wants to know if she’s done something to offend you.

What on earth is the correct thing to say?
