Memorable? I've met people from all over the globe all the time. I am white (and officially Christian) myself and I've worked for a black boss (said to be from Niger, but that's according to rumors as I never asked him) for awhile. Given private lessons to a boy from Sudan. I live in a neighborhood with loads of Muslims and I've been overloaded with food, drinks and friendly gestures on a barbecue by Muslims. I've helped one night with Syrian refugees trying to help them with mastering the Dutch language, and I've been talking with somebody who committed as serious crime because he fled from Africa but learned the hard way the Europe was not the paradise he hoped for and resorted to crime as the only way to get money for food (and he fully admitted he had been stupid).
Unlike what populists wanna make you believe, I've seen the good side of these people. Especially when I helped those refugees with the Dutch language, it was so wonderful to see how happy they were when I approved what they said as correct Dutch, as they really wanted to master it in order to be able to make their way into the Dutch society (and Dutch is not an easy language, I tell ya).
Of course, I am always interested to learn something about different cultures, in small bits of information at a time (I have trouble digesting a lot of information in once), but when judging people as persons, I couldn't care less about ethnic background. Be good to me and I'll be good to you. Be bad to me and expect me to be bad to you. Simple huh?
