she just didn't give a fuck

so me and kate started seeing each other a few weeks ago. we met at an art gallery opening thing and hit it off, like i could tell she was into my work too. anyway we've been going out but nothing serious or exclusive yet. but last night we were at her place watching some film, and there's this moment where the lead gets really intense with their lover and kate just kind of leaned over and... you know what i mean? it was totally unexpected but also kinda perfect in that moment. i didn't push back or anything, just went along. so we did stuff after that too which was cool. she's very hands on and open about everything. and today when i saw her she didn't even mention the whole thing, acted like it wasn't a big deal at all. is this normal for people? i mean it felt good but now it just seems weird to me.
