Normalising new experiences

It suddenly occurred to me yesterday how normal I find the experience of living among people from so many different cultures and countries. I went to a Greek restaurant and knew exactly what to order and how to pronounce it correctly. I did it almost unconsciously and the transaction was over quite quickly because I was so precise. (I became conscious of this because the customer before me was asking about every item and still trying to figure out what to order.) But later on, I thought to myself, how did I become this person who knows all this information? Because I didn't grow up in this setting. But now the experience is so familiar and so ingrained, I can't imagine life otherwise. The person that I was before would look upon me now and find it odd that I am familiar with the cultures, objects and tastes of so many different ethnicities and nationalities. But to the person that I am now, that is ordinary. There are so many ways in which I and so many others who have experienced these transitions in life have absorbed and processed new knowledge and new experiences, and become utterly and totally familiarised with these - in so many different domains. It's quite remarkable when you think about it but the truly remarkable thing is that you never do - it never strikes you as being noteworthy anyway. This is just the new you - the person that you are now, and you know these things, and you are expected to know these things, because this is the reality of the place you live in.
