the young teacher's 'self-identification' [='identification'] with his students
He needed to show (his) 'identification' before they would cash the check.
They had/felt a (strong) sense of 'identification with' their neighbors.
(..) Was the music too loud? We were having a celebration. Miss, I need you to button your blouse. I can tell them to turn the music down. That's not mine. Okay, we're gonna need identification. Keep your hands where we can see them. Oh, my God. You got anything else in your pockets I should know about? (..)2010 The Social Network
