Roommate is too “busy” to take out the trash

Hi! This isn’t that big of a deal, but I’d love some insight :)

I came home from work today to find one of my roommates cooking in the kitchen. The trash bag had been removed from the bin, with the full bag sitting on the ground next to it. I ask my roommate, “Oh, Are you taking out the trash? Thank you!”

To which she responds, “No, but I needed space to throw some stuff away. I’ll be too busy”

So I ask her if she has a meeting or something coming up (roommate works from home), but she says that she does at nine (four hours from now). She says that she’ll be too busy for those four hours doing things like finishing cooking, eating, maybe working out, and relaxing a little??

Obviously this rubs me the wrong way. Like in all that time with all of those different activities (ESPECIALLY just relaxing?) she doesn’t have the five minutes it takes to take the trash to the can? And she took the bag out and left it just expecting someone else to take it out? Honestly it really makes me feel like she values her own time way above everyone else in the house’s, and isn’t willing to put in the effort it takes to do something that makes everyone’s lives a little easier.

I ended up just shutting my mouth though and taking the trash out myself. I didn’t think it was worth the fight, but now I really want to say something to her. I’m worried I’ll build resentment over this incident, so am I overreacting?
