"GREASE" might have been the word that Olivia Newton-John and John Travolta were concerned about, but it's "frustration" for Tiger Graham Polak.
Balancing the frustration is the knowledge that his clash with the tram could easily have killed him, but such is human nature that it's the frustration of now that's stronger than the relief of simply being alive.
And while his progress has been terrific, it's a long way back from being in an induced coma with brain bruising to being an elite-level footballer.
Polak found himself having to relearn things he'd done all his life.
"I was doing things like speech classes, and doing rehab for things like my balance with the occupational therapists there (Epworth Hospital)," he told richmondfc.com.au.
"It was bloody hard – it was just frustrating more than anything. Just trying to remember things or do things that I knew I could do hands down if I hadn't had the accident.
"It was just frustrating that I wanted to do it, but I couldn't seem to quite remember things, or quite do things.
"It was, 'I know how to do this, what the hell is going on?'. It sounds easy, but doing it ... I feel uncoordinated with it.
"But they reckon it's going to get better over time, and I think it's gone unbelievably well at this stage. Hopefully we keep getting gradual improvement."
Polak has been hitting the gym hard, but now with training back in full swing, some days are better than others.
"I'm not doing a whole lot ... I get tired pretty easy, so Matty Hornsby (Richmond elite performance manager) down here has been really great.
"If I'm feeling bad he pulls me out, if I'm feeling alright, I just go for it.
"I've got the people from the hospital coming down on Wednesday to talk about my program. I want to do most things, that's the frustrating thing; I want to do most things but physically just can't.
"Then my hands start ... I start dropping the ball, and I think that's my best asset so I don't want to drop the ball, so I want to keep practicing that.
"But I think over time that will get better. It's a frustrating time of my life."
One of the biggest frustrations is that it was just a second's inattention that caused all the problems in the first place.
"It's probably more frustrating that I got hit by a tram out the front of my house, because I know the tram is there.
"But I just wasn't aware ... I missed the first one, but didn't see the one coming the other way. I nearly got across, and it's just frustrating how silly it was."
