Spoiler: they don't actually wish they're tall. They're just injecting how smol and cute they are into the conversation.
As a tall girl, yes it sucks. I'm not even 6' but I'm tall for a woman. Short girls love to humble brag about being smol and needing to get on stools to reach things etc... They know it's cute.
