Clint gets Agent Coulson as his handler and awaits instructions, because every other handler before thought he was undisciplined and maybe even mentally deficient. Coulson sighs and explains that he expects Clint to be a grown man who does not need to be told how to tie his shoes.
I don't remember whether it was a Clint/Phil-pairing or friendship fic.
Could somebody help me out, please?
EDIT: It's 'Falling in Love is Hard on the Knees'. Thank you!
