How would you feel if I told you I am happy my cousin was murdered?
Are you serious because why would you be happy about something like that?
I can live in her house and live for free for the rest of my life
It is horrible to be happy someone in your family was murdered. You are expected to find your own home and pay for it.
Fuck you.
I'm sorry, but it's really not wise to tell people about this. No one will think it's appropriate and everyone will just think you're evil for finding pleasure in this. I think, going forward, you should keep this feeling a secret to avoid stigma from family and friends.
