my sister keeps coming over with her kids in the middle of the day unannounced and just letting herself in to hang out with the senpai, which is a bit intrusive and seems kind of rude to me but i'm ultimately fine with it.

however, they also get a bit upset when i don't go hang out with them while they're here. they used to come bang on my bedroom door and be really aggressive about it. am i in the wrong for not dropping whatever i'm doing to go hang out with them? like it's one thing if they asked or even -told- me they were coming but to just bust in while i'm busy with something and expect me to make time for them seems so incredibly rude. it's bad enough that they're making a racket when i'm trying to work or study or god forbid just smoking a joint and enjoying a relaxing night off
