Let's call my friend, Brenda. Brenda and I have belonged to the same club for about three years. This year, Brenda became president of the club, and I feel like she's changed completely. Before becoming president, she and I would usually always make fun of the stereotypical club member. We also didn't take the club that seriously.

Over the last semester, Brenda became part of some leadership committee in the club. She complained constantly about the committee leader, Samantha.  She would text me daily bitching about something Samantha did or said. She also wanted to make a report against Samantha for being unprofessional. 

Fast forward to today, and Brenda has done a 180 on everything. She now "loves" Samantha and says stuff like "Omg, I love Samantha, but I really wish she would stop taking all the cookies". When I try and mention how much she hated Samantha just a few months ago, she'll usually just brush it off. She also now claims the club is the most important part of her life. She's always talking about how she loves all the members she used to hate, and how the club really is a meaningful organization. 

I understand changing your mind about something but completely reversing your opinion on something/someone after two years feels so artificial to me. I've also started noticing various other ways Brenda seems to change her mind to try and fit into whatever role she wants to be. AITA for thinking this new change is totally fake and that Brenda is kind of a fake person in general?
