I don't know if I posted this in the right forum, but I need advice. Ever since I pledged Alpha Gam, my mom has had something negative to say about it. I think she really hates the idea of her daughter being a "sorority girl"

I feel like she doesn't support me in my decision to go greek. After I was initiated a few weeks ago, my mom completely does not understand why I have to go to chapter meetings. She can't stand the fact that I have to be back on campus a few hours earlier so I can make it to chapter. She doesn't understand what the word "mandatory" means! She thinks that I spend all of my time doing things for AGD, when I don't.
I wrote all that to ask how you were able to win your parents over in your decision to join a GLO? Thanks in advance.
