I will let @theironfelix expand on this but looking up the dictionary definition I can see why you wanted to check. I would say its equality and something being accessible to everyone, so the question is looking at a time when you either you did something with someone/a group that changed your views, or witnesses something that had the same effect. So a poor example might be thinking girls had cooties and were boring as a kid, but then going to school with them and finding out they are just kids too. Or watching the paralympics and realising people with disabilities are just as able as anyone else. Poor examples but hopefully that gives you an idea of it, and I am sure felix will be by with a better explanation.
And yep, nana is just short for bananafish ;)
Thanks a lot, Seems I am not missing anything else than what I understood.
