It's the small things that make me swoon

There's this girl I saw first at a book club event and have run into regularly at the associated library (she is usually around at similar times as me). Massive crush from the start, my brain stops working when I see her and I have to try hard not to stare.

A bunch of us were looking through a booklist and went to locate various books. I was staring at the bookshelf for a minute when suddenly I hear her laughter behind me and her going "if you take much longer, we'll take till the weekend" before she placed her hands on my hips and gently steered me out of the way, before instantly finding the book and taking it. She then slapped me on the back and gestured for me to come before walking off.

I was straight up frozen. Something about the way she, idk, took charge in that moment and just moved me aside like that just melted me into a puddle. I think she could have literally asked me to do anything in that moment and I would have. But I think my body shut down and refused to move because she had walked halfway back before turning around to see I was still by the shelf and she asked what happened. I just had to stammer out something, could tell I was blushing.
