Don't you just hate it when you're reading a story, and the characters just have these split second mood-swings? Like, I get how someone asked you to hang out with them more, because they didn't want to lose you over you boyfriend, but don't start CRYING in a split second for heavens sake!
This might just be because I don't usually feel much of anything, but I honestly don't like it when some characters are written this way in fanfics. Especially when that character is canonically pretty stoic.
