She always injects herself into every one of my situations and even worse, injects our mom. Like seriously, we are freaking grown people, and she still wants to inject other people into things that are none of her business in the first place. I want to wring out her neck. for example, if I fail one of my classes (for the record I am no longer in high school )Hypothetically speaking of course. She will tell our mom even though it is only my business and I am 19.
