I had enough an lost it, i then messaged her saying shes disrespectful an if she makes a mess she has to pickup her shit, her response is " i helped you this week dont have a go at me over blankets n pillows lying around, go have a sleep " which PISSED ME OFF, i replied idgaf yous always make a mess and leave it for me! Its rude make a mess pick it up it aint hard! She then just said " yuh " thats it anyone else have a sister like this that doesnt take you serious!!! How do yous cope. Let me know
