I'm going to snap at my mom because I felt like she was ridiculing me
How is your mom ridiculing you?
She always tells stupid jokes that are just beneath my IQ, I'm tired of it.
Instead of snapping at her. You should talk to her about it like an adult. Your mom will respond better that way.
I can't deal with people like her.
I just don't think you should snap at her. If you don't like her jokes then just tell her that.
