I do not have to deal with our mom everyday, but i can quite understand some of what an older sibling does and has to. As sis is in her early 60's, i cannot imagine how she can sound annoyed at times at things i could just let pass by, but yes, she's with our mom everyday, so she be going thru some stuff of older generation as well, that we the younger can still strive to understand. And be brave about!
