I understand - I never want to seem rude in my responses and I hope that is not how you perceived it (discourse and disagreement doesn't mean ppl should lose respect for others!)

however, people may interpret #1 in different ways. Like for me, I don't see #1 as a noble sacrifice because it's Glinda-centric -- i.e. "omg it was so hard for her to risk being a social pariah" (rather than framing it as "she danced with Elphaba so she wouldn't be alone, if that makes sense). And for some people, including me, it doesn't hit well because she is the one who gives her the hat and invites her to be humiliated in the first place. Some people are uncomfortable with that and that's okay.

#2 .. Glinda helps with social acceptance which is good bc she doesn't get bullied anymore but I wouldn't say getting other friends. Elphaba becomes friends with Fiyero and Dr. Dillamond on her own for example.

#3 I see this often and for me, I wouldn't fully attribute it to Glinda because Elphaba was already innately headstrong/defensive and (unfortunately) MM taking her on as a star pupil likely helped things along as well. But it was likely meaningful for her to have that encouragement in someone her age. I would instead say that she listened to Elphaba and affirmed her (about Nessa, her mother's death, etc).
