Firstly, Jazzieal, what exactly is a possum? I assumed they were like a squirrel, but they sound much bigger, more like a racoon.
Actually I would just like to give you an example of how people get it so wrong and cannot live and let live.
When my ex-husband and I first came back to the UK, we had two kiddies. My eldest, was school age and the youngest had a couple of years to go before starting school. Anyway when I first took Danielle to school here, she was so unhappy there, because all the kids were calling her a "Paki". The teachers had introduced Danielle as the new kid who came from Africa, and because the other children didn't know better and had heard their parents speaking about people in a decidedly racist way, they started to call her a "Paki". The parents of course denied ever using such terms and could not understand where their kids had heard the term.
"Paki" is a very derogatory way of referring to Indian people from India and the Indian sub-continent. These kids were only about 7 or 8 and didn't know better, and could not have got it more wrong if they tried. Danielle is very light skinned, blonde and blue eyed, (definitely caucasian).
This is the way that racial tensions and hatred is passed on from one generation to another. Something else I could not believe when I came back here was just how racist the people of this country are. I was never brought up with the kind of racism that I have seen in the UK and I find it quite shocking and disgusting how hurtful people can be because they don't understand other races and don't want to make the effort to get to know them either. I wish they would try, because I think everyone's lives would be a little richer if they did.
