<human>: Let me preface by saying I'm a people pleaser and I'm working on saying no to people. I'm not really a people pleaser to my mom for the most part however. One of the situations I have trouble with, is if someone asks me to do something and they're completely capable of doing it, it just might be a little more convenient for me to do it, do I say okay or let them, since they're perfectly capable. This sounds super small, but for example a friend asked me once to turn off a lamp. The lamp wasn't far at all, but I was right by him and just a little closer, not like right by it, but a little closer. It fucked with me like, if I do it, am I being a people pleaser, and if I don't do it, am I being a dick? I know I've been taken advantage of in some situations because of my people pleasing, and I wasn't sure if this is one of them. I've chosen to just say no when I get in those situations, unless it's like way more convenient for me to do it.

Anyways me and my mom never argue and get a long really well. I was on my way to take me shower and I stopped to pet my dog on the couch. My mom was sitting right next to my dog. My mom asked me to get her some Advil. This is one of those situations where I was confused as to what to do. She was technically closer to the kitchen but I was "up". For some reason I was kinda expecting her to get upset when I didn't. But I thought of times where I asked her to get something and she told me to get up and get it myself. So I wasn't sure. Anyways I started to walk away and she was like are you serious, and then she said she didn't want to talk to me and called me selfish.

I don't know I'm pretty confused as to what to do with my mom and in situations like those. Was I being selfish, and in situations like those what should I do?

Can you condense the text into a few key points?
<bot>: My mom asked me to get Advil and I wasn't sure what a normal person would say and was trying to not be a people pleaser and now she's mad at me.
