Funny and relevant response to a test question, probably on Buzzfeed somewhere

I used to breed zebra finches. I slept through most of high school biology genetics lessons but I do know that the male finch had some sort of gene where some of the chicks, products of two different females, would hatch completely white. The parents would attempt to kill the mutated chicks once they hatched and again, I'm not a biologist, but it made me think that since the chicks had a different coloring, they were unaccepted.

On a personal level and as a third party I have seen situations where someone assumes another individual is a certain ethnicity, then actually gets upset and feels betrayed when they find out that their assumption is wrong.

An example: I became friends with a coworker and apparently she assumed I was white. A few months of hanging out and she noticed I cooked with chopsticks, heard me on the phone with my father who I address as "Ba" and a few other glaring clues that I am not actually the white girl she thought I was. She seriously got upset when it dawned on her one evening at my house and it was obvious that she felt betrayed that I hadn't revealed my mixed race background. Here she was assuming I was a white girl until she heard me on the phone with my family referring to my relatives in Chinese.

She stood up, said, "You never told me you were Chinese!" We ate dinner, I walked her to the train, and she pointedly avoided me after that day. She wasn't racist, she just felt like I had deceived her by not announcing my heritage when we became friends. Oh yeah, and she wasn't a white girl, either. Crazy. I feel sad thinking about the whole situation because it's ridiculous but apparently it's a thing.
