AIBU, which stands for 'Am I Being Unreasonable', is the perfect platform for sharing your thoughts and opinions! So, for today's AIBU discussion, we have this story from Reddit/Fit-Hunt-2476:

Am I being unreasonable for exposing my sister's fake cancer to our parents after she refused to come clean herself?

'I (34, Female) just found out that my sister (31, Female), who has been telling my whole family she has cancer for the last 8 months, has been lying. She shaved her head, said she was doing chemo, and had our parents move in to "help her through treatment". I started to have doubts when, besides also staying out late relatively frequently, she would never let anyone attend appointments with her, and she clearly had way too much energy for someone going through aggressive chemotherapy.'

'Last week, I ran into the office manager of my sister's oncologist at a coffee shop (small town). I casually mentioned my sister, and the office manager was confused; she had no idea who I was talking about. I did some digging through doctors and spoke to my sister about what I learned, and she broke down and spilt her guts.'

'It turns out she fabricated the whole story because she was in over her head with debt and wasn't able to afford her apartment anymore. The cancer story got our parents to move in, and she could then stop paying her bills.'



'I was furious and told her that she had 24 hours to tell our parents the truth or I would. She asked me not to tell them because it would ruin her relationship with them. She did not tell them, so yesterday I took everything to our parents.'

'Our parents are heartbroken. My sister is acting like I had no right to "out" her and she didn't even say this to our parents, she was going to stage a "miraculous recovery" next month. She said I ruined her life, and that family should be trying to defend each other rather than expose each other'.
