My Mum keeps nagging me to spend time with my brother. I don't dislike him but he is only 14 and to be honest I don't want to spend what little free time I have with him. However everytime I see her she keeps going on and in about it, saying things like she's never seen an older sibling show such little interest in a younger one and how he might as well be an only child and how he needs me to guide him. Although tonight it got worse with her saying that we'll only have each other when she's gone, she's only 49 FFS. AIBU to want to spend my time with who I want doing what I want without my mum trying to send me on a massive guilt trip.
