I'm going to yell at my mom for telling people about how she got pregnant with me
Why would you yell at your mom for that?
It is a sordid story I'd rather remain private.
You shouldn't yell at others. You should show your mother a little more respect.
I'm old enough to yell at her for what she did to me.
Regardless of the story, you need to not yell at your mom. Show her the proper respect she deserves from you.
