As someone who always was in the receiving end of the lazy and selfish acting of my brother, I can't agree u.u trix
Yes you're totally right same with one of mine but I would still wish for his hapiness like I wouldn't interfere with his relationships, I just don't bother with him. And yess it all depends on the degree of selfishness.
As a sister it felt sad cause I could kind of relate to his sister, she is just lazy and selfish right? Aren't we a bit all like that?
