Woman Rejects Role Of Cool Aunt Cause It's Free Babysitting

This woman decided to ask the folks of Reddit's AITA community whether or not she was in the wrong for rejecting her role as a "cool aunt" because it basically amounted to her just doing a ton of free babysitting for her entitled sister. On top of that there seems to be a solid amount of toxic family drama at play in this situation. The collective opinion would seem to be one that the cool aunt is still cool without doing all the free babysitting for her sis.
