I find it odd she will post unflattering photos of herself on her other account, but then got annoyed when Jimmy took unflattering photos of her.
I thought about this too, perhaps it is due to wanting your bf to think of you as the most attractive woman in the world and only take pics where you look your best. Taking silly pics where you look awful, well it's a reminder to him that you aren't perfect and he is the one taking them he definitely knows.
Maybe I'm on my own here, but I like the real life soph account, a nice dose of reality, of light hearted sillyness when all the insta filters, facetune and weird angles get too much. She (or any of them) aren't models, so they should just have more fun with their pics.
@Aunt Lydia I too hate (with a passion) that bouncing around thing she does when posing for insta. It always looks as if she's been on the receiving end of a cattle prod with her eyes open unnaturally wide and her lions mane full of static.
