I remember this short story off the glee angst meme that I cannot find anymore. I remember Blaine doesn't wear hair gel and this is a big thing for him after Sadie Hawkins. Kurt doesn't get it and says something insensitive and Blaine ends up storming out and walking back home alone. When Kurt gets back home, Burt informs him that Blaine's dad called saying his son had to walk home and he was disappointed in Kurt.
Ring a bell?
I'm also looking for any fics with Kurt being the supposed 'bad guy', being insensitive, ignorant, etc... preferably blangst but any type of other character angst is good with me.
