i hope i won't become like this

my maternal grandfather has been in hospital for a abt a wk because of some old age problems - he should be discharged soon. all day long my mother grumbles about having to go visit him in the hospital, and how this sibling doesnt visit much and yet the others dont say anything. and how time consuming and pointless it is to visit for an hour or so everyday when my grandfather is too weak to talk or interact much. HELLO, he's in hospital to recuperate from some sickness, how much do u expect him to say??

basically my mother is not focused on her father's recovery, but tells us about which sibling visited at what time, and for how long. and all that rubbish.
i find it so disgusting i always feel like scolding her when she talks like dat.
