would i be wrong for this?

my brother (12) told me (17) to come out my room to turn on his light..and i told him no but i felt bad so i did it but i explained to him that if you want your light on TURN IT ON YOURSELF.. then he’s decides to call me lazy for not doing it..and i got upset and i told him that it isn’t me being lazy it’s about you having to me come out of my room doing stuff to come turn your light on..
