So we are all home for Thanksgiving break and my 20yo sister's attitude already leaves much to be desired. My dad is not exactly red pill material, and he's always wanted us to be happy so he's never been strict with us. I realized his diplomacy and genteel approach early on as a teenager and respected him for it, never abusing his kindness or taking it for weakness. However, my sister frequently entices him into absolutely pointless arguments, running her mouth like a broken record, and disrespecting my dad's requests that she change her behaviour, clean up after herself, etc.

I'm often a helpless spectator in these occurrences since my dad will not take action and my sister will just eject "you're not my dad!" whenever I step in to get her to fucking clean up her shit or show some respect. I can't bring myself to physically harm her, I feel like my dad should though, because talking to her does not get the message across as she often simply leaves the room or abruptly and impolitely changes the subject. IT'S REALLY GETTING OLD YOU GUYS. And my dad just won't step it up... WHAT THE FUCK
