She will kill someone eventually and then what?
She's shown complete disregard for anyone or anything. If she cannot be arsed to grow up and parent her DC or look after animals then she has proven she doesn't care about anything other than herself.
I've got friends who have ADHD and I work with someone on the spectrum. They are decent, hard working people who contribute to society. She doesn't.
Again, I know people who are mentally unwell who do not behave like her
She needs locking up and forgotten about. All she cares about is the attention this constant chaos generates.
