[Sen's Revenge]

I think you're stuck, friend.

Yes. she is a TERRIBLE person.

But she won't be the last terrible person to join your organization.

Frankly, she's right--if she never officially joined the other sorority, then there's nothing that can be done to kick her out of the one she lawfully joined.

The only way it would work is if you actually found photos of her wearing the other organization's paraphernalia. If I was an RD, that would be enough evidence for me.

Until then, I honestly would just block her on social media. She's going to be a problem.
