I'm thinking that when your sister did this, framing you for the crime was her goooooooooooooollllll!!!!!!!

Actually poo in your mom’s bed

That seems pretty ****** up. With your bare hands? I feel like your mom needs to reevaluate her parenting mechanisms.

Is this the sort of thing you usually do as why would your mother automatically blame you?

I would have thrown it at her. that's ****** up

You should have produced a comparative sample yourself. This way, your mom would have known that this poo was not your poo. Then you would have been allowed paper towels to remove your poo while your sister removed her poo with her bare hands. Next time, don't forget to take a photo of the two samples side by side for future references.

I don't care if she was standing there with a willow switch in her hand, no way I'd do that. Sometimes parents are unreasonable and you have to stand your ground no matter the consequences. Because if you don't it will only get worse from there.
