dude, that's complex.

i think one of the charm points of glinda's character is she doesn't really seem to hold grudges against other people. if anything i argue glinda is too conflict averse and this is one of her whole problems and she could stand to be madder at the things other people do. into her later life she blames herself for stuff she knows morrible did. but it's also why people could get her incandescently mad for 2 seconds and she would just calm down after that. boq thought she was really cute when she was mad and elphaba clearly thought so too because she kept provoking her for fun. on the other hand get elphaba mad once 20 years ago and see what happens.

Glinda was 60 years old and going why did I never have any children…? Well first of all you married young, fresh out of college, and second you are probably a lesbian, and probably due to a combination of these things you chose an infertile old man. Third of all you can’t even take care of a houseplant, and I’m not even just saying that, because one time you told someone you were interested in gardening and they panned over to a desecrated potted plant nearby
