I'm going to look at my sisters reddit comments
Why do you want to look at her comments.
She's disturbing me on purpose, and  I don't know if she's trying to provoke me or she's just bored.
Those reddit comments are her private comments. They are none of your business. You shouldn't provoke her.
Maybe I should study her and maybe I should find what triggers her reddit comments. Maybe I can push them by triggering her on purpose.
This is a very cruel thing to do. If you have a problem with your sister, you should try and talk to her and work things out.
