Neither of them have steady jobs and my father is paying my brothers car insurance, on top of that they are always going out drinking or to hotels to get away from the children for a weekend. 

A few months ago they were in a motorcycle accident and she has required a few surgeries, today is suppose to be her last one. The doctors told her that she would be staying the night and instead of letting one of her daughters go with her father she has again left it to my parents who are suppose to be taking a getaway trip for my mothers birthday. Instead of my brother coming home after dropping her off for surgery hes decided to stay at the hospital for the whole 8 hours that she's in the or again forcing my mother to take the day off to play nanny.... 

It's getting to the point that I can't stand to listen to my parents talk about it and it's causing a rift in my mothers and mine relationship. I don't even like going to visit my parents because it is just so stressful. I don't know what else to do I know it may not be my place but I feel like someone has to stand up for my parents otherwise they'll just continue to be doormats..
