A guy who was two terms below me in Juniors arrived at the Regiment 6 months after I did. The guys knew he was coming and the overt racist banter came out. 'We'll stick our boots outside his room, he can clean them, he'll be used to it' sort of thing. He was the first black guy for a few years. All very mild, but racist the same.
When he arrived, it stopped in an instant. Not only was a big bugger, he was a really nice bloke and became everyone's mate. He and I hit it off and became besties.
It was amazing how the talk evaporated when they met the guy, and actually liked him and had loads in common with him.
